Prime Minister tells truth, shock: Cameron is caught on camera telling the Queen that Nigeria and Afghanistan are the most 'fantastically corrupt countries' - even though we send them both millions in aid

David Cameron made a toe-curling gaffe in front of the Queen today by boasting that he has 'two of the most corrupt countries in the world' coming to a key London summit this week.

The Prime Minister seemingly did not realise he was being filmed as he singled out Afghanistan and Nigeria for the insult.

The blunder came as he was talking to the Queen and Archbishop of Canterbury Justin Welby at an event in Buckingham Palace to mark the monarch's 90th birthday.
