The multi-millionaire son of a Tory minister who presided over the controversial "right-to -buy" scheme is a buy-to-let landlord owning scores of former council flats.
A Daily Mirror investigation found a third of ex-council homes sold in the 1980s under Margaret Thatcher were now owned by private landlords.
In one London borough almost half of ex-council properties are now sub-let to tenants.
Tycoon Charles Gow and his wife own at least 40 ex-council flats on one South London estate.
His father Ian Gow was one of Mrs Thatcher's top aides and was Housing Minister during the peak years of right-to-buy.
Other wealthy investors own scores of ex-council properties via offshore holding firms in tax havens in the Channel Islands, the GMB union has found.
Boss Paul Kenny said: "You couldn't make it up. The family of one of the Tory ministers who oversaw right-to-buy ends up owning swathes of ex-council homes."
