It’s time once again for the nation to decide who it will send to represent the UK at the 2008 Eurovision Song Contest in Belgrade.

Eurovision veteran Terry Wogan will be joined by Claudia Winkleman to host the two-part contest Eurovision – Your Decision on BBC One This Saturday which will see six acts split into three categories going head-to-head.

The line-up this year features:

* Soloists

Chart-topping songstress Michelle Gayle who goes head to head with the X Factor’s Andy Abraham, both hoping they have got what it takes to fly solo in this year’s contest.

* Girl groups

Lively pop duo LoveShy compete with soulful motown sensations The Revelations whilst aiming to strike a chord with the voting public.

* Joseph v Maria

Rob McVeigh and Simona Armstrong won the hearts of the British public as Joseph and Maria hopefuls, but which one will hit the right notes and get the votes this time around?

This year the judging panel – which will be headed up by Terry – will have an even more important role.

After each performance the panel of three judges will decide which act from each category will go through to the next round to compete for the public vote. If the other two judges can’t agree on which act should go through, Terry – with his expert knowledge on Eurovision – will have the deciding vote.

The judges will also pick a wildcard to go through and all four acts will return for the second show. The two acts with the lowest public vote will immediately leave the competition and the remaining two will sing again for their chance to go to Belgrade for the 53rd annual sing-off.

Eurovision – Your Decision will also feature a performance from Katrina formerly of Katrina And The Waves with a new remix of her 1997 Eurovision winning hit Love Shine A Light.

Terry Wogan said: “A turkey is one of the contenders for this year’s Irish entry; for the past few years, we’ve been picking a turkey for the UK. Let’s hope that the British public will make the right decision this year, and give the UK’s entry a fighting chance against the Eastern Bloc, in Belgrade in May.”

Claudia Winkleman said: “I’m very excited to be taking part this year. Standing next to Terry in a floor length sequin lime green outfit will top the evening for me. Plus if we can choose a great act and then win in Belgrade then even better.”
