David Cameron’s Christmas message has called on Lib Dems to back the Conservatives as there is between Lib Dems and Tories  ”now a lot less difference than there used to be on how to create a fairer Britain”.

He then goes on to give the game away by saying that a hung parliament would be bad for Britain – despite his apparent belief that there is not much between us and the Tories.

Mr Cameron, not for the first time, is talking double-speak and rather in bad spirit for the season og goodwill trying to put a rather distortive spin on the Lib Dems and the Tories and for that matter the next election. So let me translate this double-speak into plain english.

When Dave says there is “now a lot less difference than there used to be on how to create a fairer Britain”, what he actually means is the Conservative party can’t win the next election outright unless Lib Dem voters drop their principles and vote Tory.

When Dave says a hung parliament would be “bad for Britain”, what he means is that it would be bad for the Conservative Party.

There are many and varied policy differences between the Tories and the Lib Dems and for that matter Labour. The Tory interpretation of the word “fair” would seem pivotal in this argument.

When we talk of fair taxes, we mean for all not just millionaires, when we talk about fair green policies for a sustainable economy we mean polices that will commit to real changes to maximise our contribution to halting climate change – and it doesn’t involve pr visits to the north pole to pose with polar bears. And the Lib Dems want to see a fairer society that recognises the value that we can all contribute to society not just the privilaged few.

If David Cameron really does want a clean fight at the next elect he would do well to start applying a bit more honesty and a lot less spin.
