Two criminals who claim to have been cheated out of a £4million scratchcard win are threatening to sue Camelot over its refusal to pay up - and have enlisted the help of a lawyer once banned over chemsex drug offences, it has emerged. Mark Goodram, 36, and Jon-Ross Watson, 31, who are both from Bolton, claim to have bought the winning scratchcard from a Waitrose supermarket in Clapham, south London in April. But after attempting to claim their winnings, National Lottery chiefs found neither of the pair - who both have criminal convictions - owned a bank account. Camelot suspect the winning ticket was bought with a stolen bank card. Enraged at the decision, the jobless duo have now enlisted the help of celebrity barrister Henry Hendron - once of Strand Chambers in London - to see if they can get hold of the £4million. Jon-Ross Watson (left), 31, and Mark Goodram (right), 36, claimed victory on the lottery but Camelot has reportedly grown suspicious and refused to pay out. They have now enlisted the help of celebrity lawyer Henry Hendron to see if they can get the £4million Speaking to The Sun, Mr Hendron said: 'My clients consider Camelot are behaving in a culturally racist way by subjecting them to a level of scrutiny, checking and vetting, they would not otherwise do if the person who claimed the prize spoke in a posh accent. 'My clients take the view it is because they are working class northerners with a history.' Mr Hendron has returned to the bar following a suspension after he was convicted of drug dealing after buying £1,000 of mephedrone and GBL to sell at parties. The drugs led to the death of his teenage boyfriend. He has now told Camelot they have until Tuesday to pay up, or face possible legal action. This is despite the Lotto chiefs claiming the pair paid for the scratchcard 'using funds without the owner's consent.' And that therefore the claim was not made in 'good faith'. Mr Hendron has returned to the bar following a suspension after he was convicted of drug dealing after buying £1,000 of mephedrone and GBL to sell at parties. The drugs led to the death of his teenage boyfriend The duo had planned to buy expensive homes and enjoy Caribbean cruises before lotto chiefs became suspicious. Watson had said he was 'going to buy luxury properties and look after myself' after claiming the scratchcard win. Police are not investigating any wrongdoing in relation to the claim, and Goodram himself has previously said he will 'report' Camelot over its refusal to pay out. Both have appeared on lists of 'Bolton's Most Wanted' for alleged crimes in the area in recent years. Goodram, a father-of-two, has 22 convictions for 45 offences and was also jailed for burglary last year. Watson is reported in local media to have several convictions for offences including bank fraud. The two men denied using a stolen card to buy the ticket for the £4Million Red scratchcard game. They instead claim the card used to buy the ticket belonged to a friend and that they had no knowledge that it might be stolen. Sitting on a bench near where they bought the scratchcard, the pair told The Sun in April that they were 'partying like the millionaires we are.' The newspaper reports that the pair have been on a 'five-day bender' when they 'won' the jackpot, downing a cocktail of alcohol including, wine, lager, vodka, champagne and Jack Daniels. After discovering their scratchcard had just won them a life far from the ones they currently lived the two men sent a video to friends to express their joy. During the video the two men were seen waving their winning ticket in the air and shouting: 'Four mil! Buzzing!.. I've won four million. Stop hating'. The two men (Watson is pictured) denied using a stolen card to buy the ticket for the £4Million Red scratchcard game. They instead claim the card used to buy the ticket belonged to a friend and that they had no knowledge that it might be stolen Camelot's refusal to pay up has now reportedly led to Goodram being left homeless. A friend told The Mirror: 'You hear about rags to riches, but he has gone from the champagne lifestyle, thinking he was a millionaire, to being on the street, drinking cheap cider and hanging with beggars. Camelot has said it 'does not comment on individual prize claims', and follows 'rigorous security procedures as part of the ticket validation process'. Their jackpot was rejected on May 28. Camelot say they will not pay out to holders of stolen tickets but their website does not state the procedure for suspected stolen bank cards. Players can buy tickets in a shop with a contactless bank card and would not necessarily have been required to show any ID. Watson, pictured at King's Cross St Pancras Underground station in London, is reported in local media to have several convictions for offences including bank fraud Last year an unemployed father-of-four was refused a £200,000 lottery jackpot after being accused of having a faked 'winning' scratchcard. Camelot refused to pay up to Eric Walker, 56, saying that one of the co-ordinates on the card was 'altered'. Mr Walker insisted he won 'fair and square' and said: 'In my eyes I've won £200,000 and I'm being cheated out of the money'. The lottery organisers said an F had been altered to appear as an E and was therefore not a winning ticket. In 2016 Camelot was fined £3million by the gambling watchdog after paying out a £2.5million jackpot claim to someone with a 'deliberately damaged ticket'. The penalty – to be donated to good causes – was handed down by the Gambling Commission over a 2009 incident that went undiscovered for six years. Camelot had previously been fined £300,000 after publishing inaccurate Lotto Millionaire Raffle results on the National Lottery website for an hour, allowing them to be viewed by more than 100,000 people.
