No coincidence: 'No money' note released ahead of Spending Review

The former Chief Secretary to the Treasury, David Laws, has never before released the "no money" letter which was written by his predecessor in the Treasury, Liam Byrne.

Even when David Cameron's former communications chief, Andy Coulson, asked Mr Laws to release it - he refused.

The note reads: "Dear Chief Secretary, I'm afraid there is no money. Kind regards - and good luck!"

Today however, David Laws allowed ITV News cameras to film the letter in which Liam Byrne, the Chief Secretary to the Treasury before the 2010 general election, wrote, "I'm afraid there is no money."

It was written on 6th April 2010 - the day on which Gordon Brown called the election.

Why has David Laws released the politically sensitive letter now?

It is no coincidence that the coalition will, on Wednesday, outline its spending plans for 2015/16.

George Osborne has just agreed the budgets for every government department. He has found the £11.5 billion of cuts he was looking for.

The release of the letter - more than three years after it was written - shows how the both the Conservative and Liberal Democrats want to remind voters about the state of the nation's finances in 2010.

They hope it will help to frame the spending reductions on Wednesday. Inevitably they will lead to some unpopular cuts in many departments.

And after Labour's change of direction (Ed Balls has announced he will stick to the coalition's spending plans if Labour win in 2015) the coalition is having to rethink how it can sell it's own economic plan.
