Bengalis (Bengali: বাঙ্গালী, বাঙালি [baŋgali, baŋali] ), also rendered as endonym Bangalee, are an Indo-Aryan ethnolinguistic group originating from and culturally affiliated with the Bengal region of South Asia. The current population is divided between the sovereign country Bangladesh and the Indian regions of West Bengal, Tripura, Barak Valley of Assam, Andaman and Nicobar Islands, and parts of Meghalaya, Manipur and Jharkhand. Most speak Bengali, a classical language from the Indo-Aryan language family.

Bengalis are the third-largest ethnic group in the world, after the Han Chinese and Arabs. They are the largest ethnic group within the Indo–European linguistic family and the largest ethnic group in South Asia. Apart from Bangladesh and the Indian states of West Bengal, Tripura, Manipur, and Assam's Barak Valley, Bengali-majority populations also reside in India's union territory of Andaman and Nicobar Islands, with significant populations in the Indian states of Arunachal Pradesh, Delhi, Odisha, Chhattisgarh, Jharkhand, Mizoram, Nagaland and Uttarakhand as well as Nepal's Province No. 1. The global Bengali diaspora have well-established communities in the Middle East, Pakistan, Myanmar, the United Kingdom, the United States, Malaysia, Italy, Maldives, Canada, Australia, Japan, South Korea, and Singapore.

British Poles, alternatively known as Polish British people or Polish Britons, are ethnic Poles who are citizens of the United Kingdom. The term includes people born in the UK who are of Polish descent and Polish-born people who reside in the UK. There are approximately 682,000 people born in Poland residing in the UK. Since the late 20th century, they have become one of the largest ethnic minorities in the country alongside Irish, Indians, Pakistanis, Bangladeshis, Germans, and Chinese. The Polish language is the second-most spoken language in England and the third-most spoken in the UK after English and Welsh. About 1% of the UK population speaks Polish. The Polish population in the UK has increased more than tenfold since 2001.

Exchanges between the two countries date to the middle ages, when the Kingdom of England and the Polish–Lithuanian Commonwealth were linked by trade and diplomacy. A notable 16th-century Polish resident in England was John Laski, a Protestant convert who influenced the course of the English Reformation and helped in establishing the Church of England. Following the 18th-century dismemberment of the Commonwealth in three successive partitions by Poland's neighbours, the trickle of Polish immigrants to Britain increased in the aftermath of two 19th-century uprisings (1831 and 1863) that forced much of Poland's social and political elite into exile. London became a haven for the burgeoning ideas of Polish socialism as a solution for regaining independence as it sought international support for the forthcoming Polish uprising. A number of Polish exiles fought in the Crimean War on the British side. In the late 19th century governments mounted pogroms against Polish Jews in the Russian (Congress Poland) and Austrian sectors of partitioned Poland (Galicia). Many Polish Jews fled their partitioned homeland, and most emigrated to the United States, but some settled in British cities, especially London, Manchester, Leeds and Kingston upon Hull.

British Asians (also referred to as Asian Britons) are British people of Asian descent. They constitute a significant and growing minority of the people living in the United Kingdom, with a population of 5.76 million people or 8.6% of the population identifying as Asian or Asian British in the 2021 United Kingdom census. This represented an increase from a 6.9% share of the UK population in 2011, and a 4.4% share in 2001.

Represented predominantly by South Asian ethnic groups, census data regarding birthplace and ethnicity demonstrate around a million Asian British people derive their ancestry between East Asia, Southeast Asia, Central Asia, and West Asia. Since the 2001 census, British people of general Asian descent have been included in the "Asian/Asian British" grouping ("Asian, Asian Scottish or Asian British" grouping in Scotland) of the UK census questionnaires. Categories for British Indians, British Pakistanis, British Bangladeshis, British Chinese, British Hongkongers and other Asians have existed under an Asian British heading since the 2011 census. In British English usage, especially in less formal contexts, the term "Asian" usually refers to people who trace their ancestry to the Indian subcontinent or South Asia, contrary to other Anglosphere countries such as Australia, Canada, Latin America, and the United States, where the term "Asian" usually refers to people who trace their ancestry to East and Southeast Asia.
