On tour with David Cameron in South East Asia

David Cameron has taken in four countries in four days on his tour of South East Asia.

The prime minister has been accompanied by a plane-full of business leaders hoping to promote trade in Indonesia, Malaysia, Vietnam and Singapore.

By 2030, the region is expected to be the fourth largest single market in the world.

As he prepares for his promised EU referendum, Mr Cameron told the BBC he wanted the "best of both worlds" so the UK could trade both within and outside of Europe.

BBC political correspondent Ben Wright has been travelling with the delegation.
