Lotto bosses in Britain have refused to pay out a jackpot worth over €4 million to the winners.

Mark Goodram, 36, and Jon-Ross Watson, 31, won the £4 million (€4.6 million) on lotto operator Camelot’s Red scratchcard which cost £10 (€11.50).

After the men discovered that they held a winning ticket, they made contact with Camelot to collect their prize.

When they made contact, though, lotto bosses became suspicious about how the men had paid for the tickets.

Records showed that the winning scratch card was bought using a bank debit card.

When questioned about whose card was used, the men reportedly revealed that neither of them had a bank account.

They said that they had given the price of the scratch card to a friend who then paid for it on his debit card.

According to The Sun, those in charge of dealing with pay outs, asked Mr Watson and Mr Goodram who their friend was, and they said his name is John.

They were allegedly unable to provide John’s surname, address or phone number when it was requested.

Camelot is now investigating and has put the huge pay out on hold to verify whose debit card was used to buy the scratch card.

Goodram and Watson had already made plans for the money, including investing in property and travelling to Las Vegas.
