On the outbreak of the Second World War Solomons enlisted in the Army and resigned from the Council.
He became Organising Secretary for the Union of Liberal and Progressive Synagogues in 1946, a job which lasted eight years.
During his time in the Army Solomons took part in the Cairo Forces Parliament.
Solomons died on his 63rd birthday in Westminster hospital, leaving Labour with 313 seats in Commons, a majority of only one vote over its opposition (the Conservative Party had 303 and the Liberals 9).
[2] His death precipitated a byelection in a very marginal constituency; Labour's successful defence of the seat led Harold Wilson to call the 1966 general election.
