David Cameron turned down the chance to head the COP26 climate conference in Glasgow this November, it has emerged.

Boris Johnson discussed the idea with the former Prime Minister and offered him the opportunity to head the international climate talks, which will take place at Glasgow's SEC this November.

Mr Cameron rejected the idea, the BBC reports, preferring the role went to a current Government minister.

The role eventually went to Claire O'Neill, who was sacked earlier this week.

The revelation that the former Prime Minister was offered the role could bolster her contention she was sacked because of her criticism of Government policy.

She reportedly intends to sue the Government over her dismissal.
