The nation's favourite nerd, inventor of the curved nail file and Apprentice winner Tom Pellereau, may hail from Hampshire but like so many other rising entrepreneurs he now lives in Wandsworth.

Contacted by this paper last week, Taylor Herring, the show's PR company, confirmed he is living in the borough but refused to say where.

He has been spotted in recent weeks at Sainsbury's Putney branch, a wine bar in Clapham and is reported to play tennis locally.

This week Frank PR, the company employed by his new business partner Lord Sugar, rejected a request for an interview with the inventor saying: "Tom is turning everything down as I think he just wants to get on with the job now."

Pellereau is believed to be developing his business plan - an office chair that he claims will help stop office workers develop back problems.

But there are already suggestions that the prolific inventor may have come up with other gizmos that may prove more tempting to Lord Sugar.

He fought off stiff competition in Sunday's final from 30-year-old Helen Milligan, 32-year-old Jim Eastwood and 21-year-old Susan Ma, to win The Apprentice on Sunday night and take the grand prize- a £250,000 investment from Lord Sugar into a joint business.
