Prime Minister David Cameron has said he is willing to take part in an online debate with the other party leaders before the general election in May.
Mr Cameron has ruled out taking part in three debates planned by the broadcasters - including a final head-to-head confrontation with Labour leader Ed Miliband.
In an online interview with BuzzFeed, the PM indicated that he would be prepared to take part in a "multi-party" debate next week hosted by the website if they could get the other party leaders to agree to appear.
He suggested that he was also sympathetic to a proposal put forward by the Daily Telegraph, the Guardian and Google - which owns the YouTube website - for an online debate involving the six main UK party leaders.
"I'm up for a debate, I'm up for a multi-party debate, whether it is you, whether it is another digital debate, whether it is the TV broadcasters, that matters less to me than having a multi-party debate before the campaign gets under way," he said.
"Everyone's got to agree to it but I've said very clearly - multi-party debate before the campaign, where do I sign?"
