The 'king' of Britain's migrant hotels is raking in £4.8million per day and may become a billionaire from the money earned through housing immigrants in the UK. Graham King, a former caravan park and disco tycoon, was catapulted onto the Rich List this year after cashing in on accommodating and transporting arrivals due to the UK's migrant crisis. The 57-year-old - who has an estimated net worth of £750million - owns an Essex business which was paid £1.74billion last year and claimed this was due to the increase in refugees.
