I don't blame the Unions. They are in politics for the benefit of their members and working people, they are not in it for the ride. They have beliefs and want to fight for them.
Unlike Progress, the unions get most of their backing from their millions of members. That sounds more representative than Progress.
'Progress receives most of its backing from Lord Sainsbury, a leading donor to Mr Blair who removed financial support for Labour when Ed Miliband became leader.'
Lord Mandelson says of Progress
'?It?s forward-looking, it?s progressive, it?s modernising and it wants to commit to the best possible platform on which we can fight and win the next election. Perhaps that?s why the trade unions don?t like it.?
He doesn't seem to have a very positive view of the union movement, which was largely responsible for creating his own party, and which represents the rights of millions of working people.
