Putting David Cameron back in Downing Street is the only way British voters can have their say over Europe in an in-out referendum.

That was the rallying call to party conference today in a speech by Syed Kamall, leader of Britain's Conservative MEPs.

He said British people deserved a say on the European Union, just as Scotland had deserved its say on the United Kingdom. Status quo was not an option for either.

Dr Kamall,Conservative MEP for London,  said voters demanded real change in Europes, and stressed: "We are the only political party that will negotiate a better deal for Britain. And then give the British people an in-out referendum. Labour and Lib Dems won't. UKIP simply can't. Only Conservatives can and will deliver a referendum."

Debunking the myth of British isolation in Europe, he said Conservative leadership has repeatedly proven doubters wrong by delivering a cut to the EU budget, removing Britain from Euro bailouts and vetoing treaty change when it would have harmed British interests.

He said :"Now is the time to roll up our sleeves and make the case for more reform. We can only achieve these reforms by working with our allies across Europe.

"Our critics will falsely tell you that we are alone in this fight. Our allies come from across Europe where more people and more parties are crying out for change.

"That’s why five years ago, we formed a new political group that looks to the future rather than looking back to the past. Forward to the challenges of 2050s not solutions to problems of the 1950s.

"I stand before you as leader of The European Conservatives and Reformists Group. The third largest Group in the European Parliament.

"Our allies are looking to a Conservative government to drive change in Europe. So next May …We need Conservative  ideas setting the agenda in Europe. We need a Conservative Government with a clear majority in Westminster. We need David Cameron in Number Ten."
