The past has its part to play in politics, but the future is the only thing that really matters. This is our chance to show we get that far more than the people who want Labour to fail.

Working for then welfare secretary, John Hutton, I was passionate about Tony Blair’s drive to change the UK’s welfare and pension systems at a time when reform was difficult to sell. I gave my all when Gordon Brown asked me to work for him in Number Ten. I was a vocal supporter of David Miliband in the leadership contest. And before all that I walked David Blunkett’s dog when he was leader of Sheffield City Council and I was the son of one of his more left wing Labour councillors.

All of that helps to inform what I think today. But it is all history. Like so many thousands who want to change the world around them, we remain proud of the myriad of past allegiances developed over the years campaigning for Labour. But we are not defined by them.

Now, we are all part of a party focussed in its determination to support Ed Miliband, renew Labour’s offer to the British people and stand up for those suffering at the sharp end of aConservative economic policy that is selling future generations down the river.

I may not have put Ed first on the ballot paper in the leadership contest, but I am sure of one thing: he won a mandate to lead, and he is going to lead us as a united party into the next election.

Without plotters, wind-up stories about plots will not succeed (so long as people on our side do not fall into the trap of fighting phantoms – mounting a counter-attack against threats that just aren’t there).

So let’s all take responsibility for doing better; as Jim Murphy said yesterday, let’s roll up our sleeves, listen to our changing country, and work harder to think up the new ideas that will re-earn Labour’s right to claim and shape the centre ground of British politics.

Ed has already rightly identified the people any Labour party worthy of the name needs to speak up for: families in the middle who work hard, want to get on, and don’t want to see others get a free ride at their expense – whether at the top or the bottom of the income scale.

His speech today on that subject is important. We should do everything we can to enable it to get the hearing it deserves and give our leader the support he needs to follow it through. That focus on the future is our best bet to ensure the ambitions people have for their own lives are reflected in the ambitions for Britain we put forward at the next election.
