The £639m deal - expected to go through before the end of the year - comes as the UK prepares for a gambling revolution, sparked by last year's Gambling Act. The act allows for 17 large casinos and one Las Vegas-style ‘super casino' to be built.
As the UK's largest casino operator, Stanley Leisure is expected to be at the forefront of the changes.
FD consumer director Jonathan Brill described the agency's remit as a ‘full M&A' brief.
He said the agency had advised Genting ‘for some time on small shareholder talks, but their presence has not been great in Britain. It's the right time for Genting to get into the UK. As a result, our brief has changed completely.'
Eight sites have already been earmarked as potential locations for Britain's first super casino.
