Led Zeppelin singer Robert Plant has dashed hopes of a reunion tour by announcing he is to go on the road with country star Alison Krauss.

The pair will play a string of dates across the UK and Europe next May, and are expected to follow up the tour with a series of US shows in the summer.

Led Zeppelin fans have been calling for a full-scale tour since the band's triumphant comeback concert in London on Monday.

While guitarist Jimmy Page has indicated his willingness to reform for a tour, Plant has been reluctant to commit.

Fans on the band's official website expressed their disappointment at the news.

"Oh dear - no Led Zep tour in 2008," wrote one.

"I really am sick to my stomach," said another, while others likened Krauss to a "Yoko Ono" figure for keeping the band apart.

She and Plant released an album, Raising Sand, this year, and received much critical praise

Their tour begins on May 5 in Birmingham and will be followed by gigs in Manchester and Cardiff.

The European leg will take in Germany, Belgium, France, the Netherlands, Sweden and Norway, before ending at London's Wembley Arena on May 22.

No other dates have been announced, but Plant and Krauss have said they will tour the US as well.

However, it has been rumoured that Led Zeppelin may play a small number of shows together, including New York's Madison Square Garden and possibly the Glastonbury Festival.
