The Radio Times has reported negotiations have been taking place between a select group of top television executives and the Conservatives, under which Mr Cameron would agree to attend the first debate, while the other two would be cancelled. The magazine quotes an unnamed source close to the negotiations as saying that Mr Cameron had instead offered to take part in a number of replacement programmes. These could include a grilling by a selected audience of experts, in-depth interviews with news anchors or town-hall style question and answer sessions. "The Tories have made it clear that we could get him involved in almost anything, as long as it does not have the word 'debate' in the title," they quote a source saying. More here, external.

A Liberal Democrat spokesman says: "It's welcome news that the Conservatives have finally agreed to taking part in at least one TV debate. As we've always said, we will be there and are pleased that they are joining us. We look forward to hearing proposals from the broadcasters about how we move forward from here."

Theresa May tells the home affairs select committee the Snowden leaks caused damage to the intelligence services, adding that they had an impact on the ability of agencies to do the work they need to do.

Theresa May is being pushed on the distribution of asylum seekers across the country - the question of why some areas have lots, while others have none. She won't say whether the distribution is fair, telling the committee the government has to look at practical arrangements on accommodation. Both the current and previous governments have done it. The set up is reasonable, she says.

Theresa May says there has been a lot of work done to look at asylum claims and to work through them as quickly as possible. From April, the intention is that people will be processed within six months, the home secretary says. But more work needs to be done, she admits. The principle of giving a decision as quickly as possible is the right one, she adds.

Sources close to the broadcasters have said there has been "no formal" proposal of a single seven party debate in April which Downing St say they have "accepted" as part of discussions on wider election coverage. Sources say the discussions are still 'in flux' and haven't been fully nailed down.

Should asylum seekers be spread evenly across the country, Theresa May is asked. The home secretary says people should understand the government is looking at the issue in the right way - it has a proper process for dealing with claims.

Labour's election campaign co-ordinator Douglas Alexander says: "Based on the broadcasters' proposals we have accepted and plan to attend all three debates on April 2nd, 16th and the 30th. If the Tories have confirmed they are to attend to one of these debates then that is progress. It is one down, two to go. But no-one should be fooled: David Cameron is still running scared of a head-to-head televised debate with Ed Miliband."

She tells the committee discussions with ports have been held and trails are taking place on dealing with coaches.
