A gun battle in the East End of London leaves two dead. It sparked a political row over the involvement of then-Home Secretary Winston Churchill.

The siege of Sidney Street of January 1911, also known as the Battle of Stepney, was a gunfight in the East End of London between a combined police and army force and two Latvian revolutionaries. The siege was the culmination of a series of events that began in December 1910, with an attempted jewellery robbery at Houndsditch in the City of London by a gang of Latvian immigrants which resulted in the murder of three policemen, the wounding of two others, and the death of George Gardstein, a key member of the Latvian gang.

The East End of London, often referred to within the London area simply as the East End, is the historic core of wider East London, east of the Roman and medieval walls of the City of London and north of the River Thames. It does not have universally accepted boundaries on its northern and eastern sides, though the River Lea is sometimes seen as the easternmost boundary. Parts of it may be regarded as lying within Central London. The term "East of Aldgate Pump" is sometimes used as a synonym for the area.

The secretary of state for the Home Department, more commonly known as the home secretary, is a senior minister of the Crown in the Government of the United Kingdom and the head of the Home Office. The position is a Great Office of State, making the home secretary one of the most senior and influential ministers in the government. The incumbent is a statutory member of the British Cabinet and National Security Council.

Sir Winston Leonard Spencer Churchill was a British statesman, military officer, and writer who was Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. For some 62 of the years between 1900 and 1964, he was a member of parliament (MP) and represented a total of five constituencies over that time. Ideologically an adherent to economic liberalism and imperialism, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.
