A businessman refusing to pay £600,000 he lost in a single night at a casino has claimed he was 'too drunk to gamb;e' after being plied with shots of 54 per cent Chinese 'firewater'.

Lester Hui, 더블유비씨247 54, said he had to drink a shot of 54 per cent proof "firewater" Maotai liquor after losing the drinking game 'liar's dice' to a senior executive at Aspinall's Curzon Street casino, Mayfair, in February 2016.

By the early hours of the morning, he claims to have consumed at least a further four shots of the alcohol, and possibly as many as ten, and told the High Court in London he was 'totally gone'.

Recalling the evening, Mr Hui said the casino's vice president of international marketing Chris De Lima had provided the dice and ordered a bottle of Maotai before they began playing the drinking game.

But Mr De Lima branded the claims 'ridiculous', who instead argues the businessman was sober enough to make decisions.

Aspinall's Club Ltd - which was founded by John Aspinall in the 60s - is demanding he pay up for his losses, with lawyers having claimed he drove himself home after his evening out.

Mr Hui, though, is defending his claim on basis 'I was so drunk they should not have allowed me to gamble', adding that he ended up with the latter part of the session a blank in his memory.
