Metropolitan Police Act 1933: The Metropolitan Police Act was a 1933 Act of Parliament initiated by the Parliament of the United Kingdom.  It was largely the brainchild of Hugh Trenchard, who served as Metropolitan Police Commissioner from 1931 to 1935.  He instigated changes for the improvement of police residences known as section houses, following various reports instigated during 1932.  The report proposed sweeping changes and indirectly called into question the reliability of the police in a major emergency.  After adverse reactions in the press and questions in Parliament, the Home Secretary Sir John Gilmour stated that Trenchard's report would be published as a White Paper, giving MPs an opportunity to debate the issues.  In very quick order the White Paper was turned into a Government Bill.  The first two clauses of the Bill, which proposed to increase the number of assistant commissioners from four to five and lower the age of retirement for senior officers, did not prove too controversial.  However, the clauses which set out limitations on membership of the Police Federation were hotly debated and characterized by left-wing politicians as "fascist".  Additionally, the proposed introduction of ten-year employment terms for some new constables was met with considerable opposition.  The bill was enacted in 1933 as the Metropolitan Police Act.

Metropolitan Police District: The Metropolitan Police District (MPD) is the police area which is policed by the Metropolitan Police Service in London.  It currently consists of the Greater London region, excluding the City of London.  The Metropolitan Police District was created by the Metropolitan Police Act 1829 as an ad hoc area of administration because the built-up area of London spread at the time into many parishes and counties without an established boundary.  The district expanded as the built up area grew and stretched some distance into rural land.  When county police were set up in England the forces of Essex, Hertfordshire, Kent and Surrey did not include those parts of the counties within the MPD and Middlesex did not have a county force.  Similarly, boroughs in the MPD that elsewhere would have been entitled to their own police force did not have them.
