Gambling company Camelot is to part ways with its chief executive and chairman when it is taken over by rival Allwyn Group months after losing the National Lottery licence.

Sir Hugh Robertson will step down as chairman, a role that he has held since 2018, while Nigel Railton leaves after six years in the top job and more than two decades with the business.

The shake-up at the top comes as Allwyn is expected to close the acquisition of Camelot next month. The two companies announced a deal in November which ended months of legal dispute.

Camelot had held the National Lottery licence since 1994 but will lose it to Allwyn from February next year.
