Jack Straw's son, who is embarking on his own career in politics, has posted a tribute to his father on Twitter:
The junior Mr Straw is hoping to be elected for Labour in the Lancashire constituency of Rossendale and Darwen, which neighbours his father's soon-to-be-vacant seat of Blackburn.
Will Straw, the son of former Foreign Secretary Jack Straw, has been selected as the Labour candidate for the Rossendale and Darwen seat at the next general election.
The constituency's incumbent MP is the Conservative Jake Berry, currently parliamentary private secretary to cabinet minister Grant Shapps.
Jack Straw, now 67, served as Home Secretary and Foreign Secretary under Tony Blair and Lord Chancellor under Gordon Brown.
