Jack Straw's son, who is embarking on his own career in politics, has posted a tribute to his father on Twitter:
I'm immensely proud of my Dad as he announces he'll be stepping down at the next election after 36 years as Blackburn's MP.
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.
