DAVID CAMERON is to lead a billion dollar investment initiative between the UK and China.

Cameron will take charge of the £750 million fund to improve ports, roads and rail networks between China and its trading partners.

The former prime minister played a key role in efforts to boost trade links with Beijing while he was in Downing Street.

Chancellor Philip Hammond welcomed his new role during an official visit to China.

The private fund is supported by the British Government but will not involve any taxpayers' money.

A spokesman for Cameron said the former prime minister's role had been discussed with the Advisory Committee on Business Appointments, which considers roles taken up by ex-ministers.
