Metropolitan Police District in the context of "Municipal Borough of Walthamstow"

Leyton (/ˈleɪtən/ LAY-tən) is a town in East London, England, within the London Borough of Waltham Forest. It borders Walthamstow to the north, Leytonstone to the east, and Stratford to the south, with Clapton, Hackney Wick and Homerton, across the River Lea, to the west. The area includes New Spitalfields Market, Leyton Orient Football Club, as well as part of the Queen Elizabeth Olympic Park. The town consists largely of terraced houses built between 1870 and 1910, interspersed with some modern housing estates. It is 6.2 miles (10 km) north-east of Charing Cross.

It was historically part of the ancient parish of Leyton St Mary in the Becontree hundred and part of the ancient county of Essex. The town expanded rapidly in the late 19th century, forming part of the conurbation of London and becoming a suburb, similar to much of south-west Essex. It became part of the Metropolitan Police District in 1839 and has been part of the London postal district since its inception in 1856. The parish became an urban district in 1894 and gained municipal borough status in 1926. In 1965, it merged with the neighbouring municipal boroughs of Walthamstow and Chingford to form the London Borough of Waltham Forest, a local government district of Greater London.

The Metropolitan Police Service (MPS), commonly known as the Metropolitan Police, Met Police, or the "Met", is the territorial police force responsible for law enforcement and crime prevention within Greater London. In addition, it is responsible for specialised tasks throughout the United Kingdom, such as dealing with counter-terrorism throughout the UK, and the protection of certain individuals, including the monarch, royal family, governmental officials, and other designated figures. It is also referred to as an eponym as "Scotland Yard" or "the Yard", after the location of its original headquarters in Great Scotland Yard, Whitehall, in the 19th century. The Met is presently headquartered at New Scotland Yard, on the Victoria Embankment.

The main geographical area covered by the Met, the Metropolitan Police District, consists of the 32 London boroughs, and excludes the square mile of the City of London – a largely non-residential and financial district, overseen by the City of London Police. As the force responsible for the majority of the UK's capital, the Met has significant responsibilities and unique challenges, such as protecting 164 foreign embassies and High Commissions, policing London City and Heathrow airports, protecting the Palace of Westminster, and managing a higher volume of protests and events than any other British police force, with 3,500 such events in 2016.
