The four artists competing for the 2006 Turner Prize learn the judge's decision on Monday, 4 December.

Work by Tomma Abts, Phil Collins, Mark Titchner and Rebecca Warren is on display at London's Tate Britain gallery.

The prize was established in 1984 and is given for outstanding work by British artists under the age of 50.

Phil Collins has set up a production company and research office - the first time there has been a "live" exhibit.

Mr Collins also made a film about people whose lives had been ruined by appearing on talk shows and makeover shows.

A number of sculptures by Rebecca Warren, who has had solo exhibitions in New York and Cologne, are on display.

Nominee Mark Titchner is known for using a wide range of media, including light boxes and hand-carved contraptions.

The four nominees are vying for an award which was won last year by artist Simon Starling.

All works will be judged by a panel including Observer journalist Lynn Barber and Tate director Nicholas Serota.

All of the work is on display until 14 January 2007. The winner of the prize takes home �25,000.
