Artist Tracey Emin wipes away tears as she unveils her £2.54 million unmade bed

Tracey Emin was forced to wipe away tears as she unveiled her £2.54 million unmade bed on its return to its "home" at the Tate.

My Bed - complete with discarded condoms - became notorious when it was shortlisted for the Turner Prize and displayed at Tate Britain in 1999.

Over 15 years later, it is back at the gallery on a long-term loan for at least 10 years.

Emin admitted that unlike the chaotic-looking installation, which features empty vodka bottles, cigarette butts, stained sheets and discarded underwear, her bed at home is now a different affair.

"I make my bed every day. It's so boring, it's very neat. I'm really OCD (obsessive compulsive disorder)," she said.Wiping away tears, the artist said that seeing the work - which is now subject to rigorous security in the form of a sensor and a guard to prevent visitors from getting too close - left her emotional.

The work, which expressed the artist's suicidal depression following a relationship breakdown, is displayed in its own room alongside two paintings by Francis Bacon and six nude drawings by Emin which she has given to the Tate.

Emin said she felt validated seeing the installation on display alongside works by some of Britain's "greats" after all the criticism about the bed at the time.
