David Cameron arrives at Tory party conference amid anti-austerity protests

David Cameron has arrived at the Tory party conference in Manchester amid protests at the Government's austerity measures.

The Prime Minister did not speak to waiting reporters as he arrived at the Midlands hotel in the city centre.

Outside the secure zone surrounding the hotel and Manchester Central conference centre, a handful of demonstrators staged a noisy protest.

Thousands of protesters are expected to take part in a march on Sunday as the conference formally opens, while Labour leader Jeremy Corbyn is expected to address a public meeting in Manchester on Monday.

The issue of Europe looks set to dominate the agenda, with Cabinet ministers making high profile interventions ahead of the gathering.

Foreign Secretary Philip Hammond warned Britain will vote to reject a new deal with Brussels unless the European Union agrees to "substantial" permanent reforms.

He told the Daily Telegraph the British public would deliver "a raspberry" to the Government if Mr Cameron's efforts to renegotiate the relationship with the EU did not secure "robust" changes.

Both Mr Hammond and Business Secretary Sajid Javid stressed that the Prime Minister had ruled nothing out - indicating he could be prepared to recommend a British exit from the EU if he failed to secure key reforms.

Work and Pensions Secretary Iain Duncan Smith said the twin crises of mass migration and Greek debt have hit the EU like an "an out-of-control bulldozer" and made leaders on the continent more receptive to Mr Cameron's drive for reform.
