ONE of the most controversial works of art of the last 20 years is going under the hammer when Tracey Emin's unmade bed is expected to sell for more than £1 million at auction.

The work, called My Bed, caused a stir when it was shortlisted for the 1999 Turner Prize although Emin eventually lost out to artist-turned-film director Steve McQueen.

The unmade bed, littered with condoms, cigarette packets and underwear, divided the critics but began the process that saw her become one of the country's most famous artists.

It was sold to multimillionaire art dealer Charles Saatchi, who is selling it at Christie's in London on July 1. It is being sold with an estimated value of £800,000 to £1.2 million.
