Britain to spend £17m on Calais border control as Cameron backs demolition of Jungle camp

* Prime Minister announces £17m investment in Calais security at summit

* He promises to 'break the business model' of criminal smugglers bringing people to Europe

* President Hollande makes no reference to France ending UK border controls in France

* Both leaders make play for Britain to remain in EU

Speaking at the Anglo-French summit in Amiens, France, David Cameron said they will invest a further £17m on security at Calais to help the French police cope with the number of migrants.

He said the money would be used to move people from camps into more permanent accommodation and deport people to their home countries who do not need protection.

President Hollande was standing firm on the notion the two countries give each other added strength on global threats, terrorism and tackling Islamaphobia, and echoed the Prime Minister on the importance of a joint effort to deal with refugees at Calais and Dunkirk.

However when asked if the Calais border agreement could be ripped up, as has been inferred by French finance minister Emmanuel Macron in the Financial Times today, President Hollande chose not to answer.

Mr Cameron said this afternoon: "It is very important for people to know that if they come to Calais, it's not a waiting room for them to come the United Kingdom.

"I applaud the action the French Government is taking to deal with the situation with the camps in Calais and say to people they should be seeking asylum in France and if they are not seeking asylum they should returned to the countries from which they came. The President has my 100% backing."

The Prime Minister also announced he will speak to Vladimir Putin alongside the German Chancellor and French President tomorrow in another plea to for him to drop his backing of Syrian President.

The three heads of state will hope their combined force will send a strong message from the EU that Russia's actions in Syria will not be tolerated.

The Prime Minister said EU membership helps to 'amplify our strength' against such complex global issues.

Mr Cameron said: "We welcome the latest truce [in Syria]. It could provide an opportunity to make progress and at next week's peace talks."

"But these will only succeed if there's a change in behaviour by the Syrian regime and by its backers.

"That is why tomorrow Francois and I together with Angela Merkel will speak with President Putin.

"Russia needs to end its attacks on Syrian civilians and the moderate opposition and accept there has to be a transition away from Assad to a new leader who can reunite Syria and bring peace and stability to that country."

The two headds of state also unveiled a £1.5 billion project to build a prototype of new drones. The UK will commit around £750 million, with the French matching the contribution.

UK companies including BAE Systems, Selex ES and Rolls Royce and Dassault Aviation, SNECMA/Safran and Thales in France are expected to benefit from the project.
