Scottish Parliament in the context of "Loch Lomond and The Trossachs National Park"

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. Since 1999, varying degree of powers have been devolved to the devolved national parliaments of Northern Ireland, Scotland, and Wales. Each devolved parliament has different devolved powers, with Scotland being the most powerful amongst the three devolved parliaments. The central UK Parliament retains the power to legislate in reserved matters, including broadcasting, defence, and currency.

It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.

Parliamentary sovereignty is a longstanding concept central to the functioning of the constitution of the United Kingdom, but which is also not fully defined and has long been debated. Since the subordination of the monarchy under parliament, and the increasingly democratic methods of parliamentary government, there have been the questions of whether parliament holds a supreme ability to legislate and whether or not it should.

Parliamentary sovereignty is a description of the extent to which the Parliament of the United Kingdom has absolute and unlimited power. It is framed in terms of the extent of authority that parliament holds, and whether there are any sorts of law that it cannot pass. In other countries, a written constitution often binds the parliament to act in a certain way, but there is no codified constitution in the United Kingdom. In the United Kingdom, parliament is central to the institutions of state. The concept is exclusive to the UK Parliament and therefore does not extend to the Scottish Parliament, the Senedd and the Northern Ireland Assembly.

Scotland is a country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent islands, principally in the archipelagos of the Hebrides and the Northern Isles. In 2022, the country's population was about 5.4 million. Its capital city is Edinburgh, whilst Glasgow is the largest city and the most populous of the cities of Scotland. To the south-east, Scotland has its only land border, which is 96 miles (154 km) long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south. The legislature, the Scottish Parliament, elects 129 members to represent 73 constituencies across the country. The Scottish Government is the executive arm of the devolved government, headed by the first minister, who chairs the cabinet and is responsible for government policy and international engagement.

The Kingdom of Scotland emerged as an independent sovereign state in the 9th century. In 1603, James VI succeeded to the thrones of England and Ireland, forming a personal union of the three kingdoms. On 1 May 1707, Scotland and England combined to create the new Kingdom of Great Britain, with the Parliament of Scotland subsumed into the Parliament of Great Britain. In 1999, a Scottish Parliament was re-established, and has devolved authority over many areas of domestic policy. The country has its own distinct legal system, education system and religious history, which have all contributed to the continuation of Scottish culture and national identity. Scottish English and Scots are the most widely spoken languages in the country, existing on a dialect continuum with each other. Scottish Gaelic speakers can be found all over Scotland, but the language is largely spoken natively by communities within the Hebrides; Gaelic speakers now constitute less than 2% of the total population, although state-sponsored revitalisation attempts have led to a growing community of second language speakers.

Since 1922, the United Kingdom has been made up of four countries: England, Scotland, Wales (which collectively make up Great Britain) and Northern Ireland (variously described as a country, province, jurisdiction or region). The UK prime minister's website has used the phrase "countries within a country" to describe the United Kingdom.

Although the United Kingdom is a unitary sovereign state, it contains three distinct legal jurisdictions in Scotland, England and Wales, and Northern Ireland, each retaining its own legal system even after joining the UK. Since 1998, Northern Ireland, Scotland, and Wales have also gained significant autonomy through the process of devolution. The UK Parliament and UK Government deal with all reserved matters for Northern Ireland, Scotland, and Wales, but not in general matters that have been devolved to the Northern Ireland Assembly, Scottish Parliament, and Senedd. Additionally, devolution in Northern Ireland is conditional on co-operation between the Northern Ireland Executive and the Government of Ireland (see North/South Ministerial Council) and the British Government consults with the Government of Ireland to reach agreement on some non-devolved matters for Northern Ireland (see British–Irish Intergovernmental Conference). England, comprising the majority of the population and area of the United Kingdom, does not have its own devolved government, and remains fully the responsibility of the United Kingdom Parliament centralised in London. In July 2025, the council of the English county of Cornwall backed a motion calling for Cornwall to be regarded as the UK's fifth nation.

A private member's bill is a bill (proposed law) introduced into a legislature by a legislator who is not acting on behalf of the executive branch. The designation "private member's bill" is used in most Westminster system jurisdictions, in which a "private member" is any member of parliament (MP) who is not a member of the cabinet (executive). Other labels may be used for the concept in other parliamentary systems; for example, the label member's bill is used in the Scottish Parliament and the New Zealand Parliament, the term private senator's bill is used in the Australian Senate, and the term public bill is used in the Senate of Canada. In legislatures where the executive does not have the right of initiative, such as the United States Congress, the concept does not arise since bills are always introduced by legislators (or sometimes by popular initiative).

In the Westminster system, most bills are "government bills" introduced by the executive, with private members' bills the exception; however, some time is set aside in the schedule for reading such bills. They may be introduced by non-ministerial MPs from government-supporting parties (backbenchers), by members of opposition parties (frontbencher or backbencher), or by independents or crossbenchers. The Israeli Knesset has a long history of enacting private members' bills: a slight majority of the laws passed by it originated as private members' bills, and thousands more are introduced without being passed. In contrast, the Oireachtas (parliament) of the Republic of Ireland rarely passes private members' bills, with the overwhelming number of bills being passed being introduced by members of the cabinet.

Edinburgh is the capital city of Scotland and one of its 32 council areas. It is located in southeast Scotland and is bounded to the north by the Firth of Forth and to the south by the Pentland Hills. Edinburgh had a population of506,520 in 2020, making it the second-most-populous city in Scotland and the seventh-most-populous in the United Kingdom. The wider metropolitan area had a population of 912,490 in the same year.

Recognised as the capital of Scotland since at least the 15th century, Edinburgh is the seat of the Scottish Government, the Scottish Parliament, the highest courts in Scotland, and the Palace of Holyroodhouse, the official residence of the British monarch in Scotland. It is also the annual venue of the General Assembly of the Church of Scotland. The city has long been a centre of education, particularly in the fields of medicine, Scottish law, literature, philosophy, the sciences and engineering. The University of Edinburgh was founded in 1582 and is now one of three universities in the city. The financial centre of Scotland, Edinburgh was in 2020 ranked the second-largest financial centre in the United Kingdom, the fourth-largest in Europe, and the thirteenth-largest in the world in the Global Financial Centres Index.

Orkney (/ˈɔːrkni/), also known as the Orkney Islands, is an archipelago off the north coast of mainland Scotland. The plural name the Orkneys is also sometimes used, but locals now consider it outdated. Part of the Northern Isles along with Shetland, Orkney is 10 miles (16 km) north of Caithness and has about 70 islands, of which 20 are inhabited. The largest island, the Mainland, has an area of 523 square kilometres (202 sq mi), making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney's largest settlement, and also its administrative centre, is Kirkwall.

Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council.

Shetland, also called the Shetland Islands, is an archipelago in Scotland lying between Orkney, the Faroe Islands, and Norway, marking the northernmost region of the United Kingdom. The islands lie about 50 miles (80 kilometres) to the northeast of Orkney, 110 mi (170 km) from mainland Scotland, and 140 mi (220 km) west of Norway.

They form part of the border between the Atlantic Ocean to the west and the North Sea to the east. The islands' area is 1,467 km (566 sq mi) and the population totalled 23,190 in 2024. The islands comprise the Shetland constituency of the Scottish Parliament. The islands' administrative centre, largest settlement and only burgh is Lerwick, which has been the capital of Shetland since 1708, before which time the capital was Scalloway. Due to its location, it is accessible only by ferry or flight with an airport located in Sumburgh as well as a port and emergency airstrip in Lerwick.

Scots law (Scottish Gaelic: Lagh na h-Alba) is the legal system of Scotland. It is a hybrid or mixed legal system containing civil law and common law elements, that traces its roots to a number of different historical sources. Together with English law and Northern Irish law, it is one of the three legal systems of the United Kingdom. Scots law recognises four sources of law: legislation, legal precedent, specific academic writings, and custom. Legislation affecting Scotland and Scots law is passed by the Scottish Parliament on all areas of devolved responsibility, and the United Kingdom Parliament on reserved matters. Some legislation passed by the pre-1707 Parliament of Scotland is still also valid.

Early Scots law before the 12th century consisted of the different legal traditions of the various cultural groups who inhabited the country at the time, the Gaels in most of the country, with the Britons and Anglo-Saxons in some districts south of the Forth and with the Norse in the islands and north of the River Oykel. The introduction of feudalism from the 12th century and the expansion of the Kingdom of Scotland established the modern roots of Scots law, which was gradually influenced by other, especially Anglo-Norman and continental legal traditions. Although there was some indirect Roman law influence on Scots law, the direct influence of Roman law was slight up until around the 15th century. After this time, Roman law was often adopted in argument in court, in an adapted form, where there was no native Scots rule to settle a dispute; and Roman law was in this way partially received into Scots law.
