David Cameron and Boris Johnson reject donation claims

David Cameron and Boris Johnson have rejected calls to pay back a £160,000 donation to the Conservatives from the wife of a former member of President Putin's government.

The money was pledged at a fundraising event in exchange for a tennis match with the Prime Minister and London Mayor.

Both Mr Cameron and Mr Johnson told the BBC that Lubov Chernukhin was not associated with Mr Putin and was now a British citizen.
