OVER 60 Tory rebels vowed yesterday to block any attempt by George Osborne to push through £30 billion austerity cuts if Britain leaves the EU.

The Chancellor insists he would be forced to raise taxes and slash NHS and education budgets to fill a multibillion-pound “black hole” in public finances.

But the blackmail bid backfired after 65 pro-Brexit Tory MPs pledged to vote against the so-called emergency Budget, enough for the government’s wafer-thin Commons majority to disappear.
