The “profligate” son of a former factory worker who made a claim on his father’s £101million lottery windfall following a drunken row at his stepmother's birthday party, has been reprimanded by a judge who said he had no right to demand an endless supply of cash.

Michael Dawes, an ex-Royal Navy officer, was accused of living "some sort of Walter Mitty existence" following his father’s astonishing Euromillions win, spending way beyond his means.

Mr Dawes, 32, was given nearly £1.6 million within two years but made the mistake of believing that the money would keep on rolling in. He spent between £20,000 and £30,000-a-month, with an “astonishing” £1,000 weekly grocery bill.

When his father, Dave Dawes, 53, became concerned about his son’s level of spending and stopped topping up his bank balance, Michael and his civil partner James Beedle, 34, took legal action, accusing him of withholding money despite promising he would "always be looked after".
