The Con-Dem coalition’s collapse quickened yesterday when Tory PM David Cameron accused his Lib Dem partners of “being all over the place” economically.

In an email to Tory MPs that was leaked to the press, Mr Cameron said the party was “unable to decide” whether it believed in austerity or not.

The PM also made a provocative comparison between his coalition partners and Ukip, saying that both were prepared to “prop up a failing Labour government.”
