The world's ten most corrupt countries have received £2.7 billion in British aid during David Cameron's time as Prime Minister, according to official figures.

Since Mr Cameron became Prime Minister in 2010, the amount spent by the Department for International Development (DFID) on aid for the nations ranked worst for corruption has increased by 14 per cent, the Daily Telegraph reports.

He singled out the two states as "possibly the two most corrupt countries in the world" in comments to the Queen recorded by ITV News.
