A reported rift between Robert Plant and Jimmy Page is thought to be the reason why Led Zeppelin have failed to announce further reunion shows.

It's claimed that Plant was angered when his guitarist failed to acknowledge him when he collected the band's Best Live Act honour at the Mojo Awards last month.

Page delivered a lengthy speech at the ceremony but didn't once refer to Plant, who was touring with singer Alison Krauss at the time.

“Robert was really disappointed that he didn’t merit a mention,” a source told the Sun newspaper.

“The award was for the band’s performance, so he thought he should have at least been thanked.”

Led Zeppelin's reunion show in London last December was one of the most widely anticipated concerts in history.

As previously reported, Plant and Krauss were among the 12 acts who have been nominated for this year's Mercury Music Prize.

They will join the likes of Radiohead and Last Shadow Puppets when the award is handed out in September.
