UK Prime Minister David Cameron is to hold face-to-face talks with US President Barack Obama, with the BP oil spill, Afghanistan and the global economy set to dominate.

The talks will take place in Canada on the fringes of the G8 and G20 summits.

Mr Cameron has told journalists there that he wants to see UK troops out of Afghanistan within five years.

The men may also discuss UK spending, amid Mr Obama’s concerns that cuts in Europe may delay the global recovery.

President Obama has warned G20 leaders not to withdraw economic stimulus packages too early.

But on Friday Mr Cameron said there was “no difference” between the US and UK on plans for quick government spending cuts.

Mr Cameron said the US accepted that those with the biggest deficits had to “accelerate the process of dealing with them”.

And Germany’s Chancellor Angela Merkel has insisted that Europe’s leaders are making good progress in talks with the US about how to bolster fragile economic growth.
