An unknown UK winner has come forward to claim the EuroMillions £123 million (US$156M) jackpot today.

A British lottery ticket holder has claimed the £123m EuroMillions jackpot and is choosing to remain anonymous after nearly two weeks of mystery over the third-biggest win ever.

The operator of the National Lottery, Camelot, said it had received a claim for £123,458,008 after the jackpot prize was won from the draw on June 11.

It is the third biggest amount ever to be scooped and the fourth EuroMillions jackpot win this year, reported the Daily Mail.

Camelot said it had a duty of care to protect the anonymity of all National Lottery winners and that it would not release further details about the ticket holder's claim.

Andy Carter, senior winners' adviser at National Lottery, said: 'This is the third biggest win ever on The National Lottery and we now look forward to helping the ticket-holder start to enjoy their new-found wealth.'

Camelot did not say whether it was an individual winner or a syndicate.
