David Margesson the
Conservative MP for Rugby and
Secretary of State for War had been dismissed from his ministerial job after the loss of
Singapore to the
Japanese, but was
ennobled as
Viscount Margesson. The major parties had an agreement not to contest by-elections in seats held by any of their members, but Brown stood as an
independent candidate in the
Rugby by-election on 29 April, and was returned as the
independent MP for Rugby. Brown was re-elected at the
1945 general election as an Independent MP against both Conservative and Labour opposition. However, at the
1950 general election, he stood again as an independent, but came third with 20% of the vote. The seat was gained for Labour by
James Johnson. In 1951 he ran against
Edith Summerskill at
Fulham West, with the Conservatives standing aside for him. He lost narrowly. ==Notes==
