HOUSE OF COMMONS
The House of Commons of England evolved in the 13th and 14th centuries. It eventually became the House of Commons of Great Britain after the political union with Scotland in 1707, and assumed the title of "House of Commons of Great Britain and Ireland" after the political union with Ireland at the start of the 19th century. The "United Kingdom" referred to was the United Kingdom of Great Britain and Ireland from 1800, and became the United Kingdom of Great Britain and Northern Ireland after the independence of the Irish Free State in 1922. Accordingly, the House of Commons assumed its current title.
It has its own post office that serves the politicians and Lords.
This office was situated at No 5 Bellevue Road Wandsworth Common
