Coldplay singer Chris Martin has said it is unlikely his chart-topping band will play at Glastonbury this year.

"I think Glastonbury is bored of us," he told BBC 6Music. "I don't think we can even take a harmonica down there for a good 15 years."
Coldplay were among the headliners when the festival was last held in 2005, but chances of a quick return seem slight.
"We might go, but you've got to know when you are welcome and when you're not," said Martin.
The Who, the Arctic Monkeys and Bjork are the only acts so far confirmed for Glastonbury, which takes place from 22-24 June.
More than 100,000 people signed up when the summer music festival's ticket registration system opened on Thursday.
The Chemical Brothers, Eric Clapton, Madness, The Kooks and the Scissor Sisters are among those rumoured to be performing.
However, festival organiser Michael Eavis has firmly denied suggestions that Irish supergroup U2 will be on the bill.
