John Wilson and his wife Michelle bought the run-down three-storey Edwardian detached house in Wimbledon four years ago. But Paul Coleman, a tenant for 29 years, refused to move out. After a hearing which contained allegations of bugging, a judge has ordered him to leave in a month's time. He now faces a legal bill for £35,000. Kingston Crown Court heard Dr Wilson, a father of four, wanted to convert the property into one home.
