– Nick Clegg, Deputy Prime Minister
I would never begrudge a politician the right to take a change of direction in their own life and that of their families if they wish to.
It seems to me he was one of the big characters in Labour who understood that an opposition can't just shout at a Government. An opposition also needs to come up with its own alternative.
So, to that extent I think it is a real loss to the Labour Party that he is no longer around making that point within Labour Party circles.
The former foreign secretary David Miliband told ITV News "I am quitting politics" as he announced he is resigning as an MP to become the head of a US charity. He admitted life was "tough" after losing the Labour leadership contest to his brother.
