I thought I'd take up the challenge and ask my readers if they know who the oldest suriving ex Labour and Conservative MPs are, or indeed, if there are any surviving minor party MPs who can lay claim to the title of oldest surviving MP?
I'll update this post with your nominations.
UPDATE: David Boothroyd has
The oldest ex-Conservative MPs are James Allason (C, Hemel Hempstead 1959-74), b. 6/9/12, and Reader Harris (C, Heston and Isleworth 1950-70), b. 4/6/13.
The oldest ex-Labour MP is Michael Foot (Plymouth Devonport 1945-55; Ebbw Vale 1960-83; Blaenau Gwent 1983-92), b. 23/7/13.
The oldest ex-minor party MP is Ernest Millington of Common Wealth (later joined the Labour Party), who was elected for Chelmsford in April 1945 (b. 15/2/16).
The oldest ex-Liberal MP is indeed Lord Mackie of Benshie; followed by Clement Freud (b. 24/4/24) and Emlyn Hooson (b. 26/3/25).
UPDATE: Chris disagrees. He nominated William Wilson, Labour MP, b.28/06/1913, MP for Coventry South 64 to 74 then Coventry South East 74 to 83
UPDATE: Liberal England has found an older Labour MP... There is an older living Labour MP: Ted Short, born 17 December 1912. Thanks to a comment on Michael Crick's blog for this.
