leader Sir Vince Cable, who turns 75 this year, is conscious of staying fit. ‘When I was in the Cabinet my dancing kept me sane. Now I do lots of cycling and I go to the gym twice a week,’ he tells me. ‘these are things you have to do when you get to your 70s because if you don’t, then you gradually fall apart. I’m still trying to do my dancing. Having got a ten from Len when I was on Strictly really did boost my confidence.’
