Mr Hain said he was pleased to get such support as it was not possible - mathematically speaking - for all six declared contenders to get on the ballot paper. (BBC News: Deputy contenders claim support)Clearly he's not very good at maths. So here's a simple maths lesson for him.
There are 352 Labour MPs.
Each candidate for the Deputy Leadership requires the support of 45 MPs (including themselves).
352 divided by 45 is 7.8222222222222222222222222222222
So it is possible for seven candidates to be nominated.
And Peter Hain has got his sums wrong. Let's hope he's never made Chancellor of the Exchequer.
