Party Leaders Arrive For Debate Showdown

Party leaders are arriving at ITV's studios for a TV showdown which will mark the only time David Cameron and Ed Miliband will debate each other in the General Election campaign.

The two-hour event sees the Prime Minister, the Labour leader and Nick Clegg joined by the leaders of UKIP, the Greens, the SNP and Plaid Cymru for a live debate before a 200-strong studio audience in Salford.

The event is the first and only debate featuring all the leaders to be held before voters go to the polls on 7 May and has the potential to shape the course of the remaining five weeks of campaigning.

During the debate - which is hosted by ITV - the leaders will give an uninterrupted one-minute answer to each question posed by the audience.

There will then be up to 18 minutes of debate for each question. ITV said "four substantial election questions" will be addressed in all.

Leaders will not be given advance notice of the questions, which have been selected by an "experienced editorial panel".

Sky News will broadcast the debate live from 8pm until 10pm, with coverage also available online and via Sky News apps .

Greens leader Natalie Bennett will make the first opening statement, while Mr Cameron is scheduled to speak last.

Speaking in Manchester, Ms Bennett said she was sure she wouldn't suffer another "brain fade" after the "excruciating" LBC interview in which she could not remember the details of the party's housing policy.

She said: "Well, I haven't got a bad cold this time and I've prepared and preparations have been well in hand."

Campaigning is expected to be largely placed on hold today as the party leaders make their final preparations for the event.

Key issues in the first three days of the campaign have included the battle between the Conservatives and Labour over economic policies and support for business.

Labour has been campaigning heavily on the use of zero-hours contracts , saying it will outlaw "exploitative" contracts if it wins power.

The Liberal Democrats have sought to highlight mental illness as a major issue.

Speaking at Bishopbriggs in East Dunbartonshire on Wednesday, Mr Clegg insisted he would not be losing any sleep ahead of tonight's event.

"I have been in politics long enough now to know that you shouldn't over-think these things or over-rehearse them," he said.

"I will try and answer the questions as best as I can and make sure that the Liberal Democrat voice is heard loud and clear in the cacophony of other political voices that will be represented on that stage."

Mr Cameron is also apparently relaxed about the debate, according to his wife Samantha who spoke as she made a solo appearance on the campaign trail in the Rochester and Strood constituency.

Asked how her husband was feeling, Mrs Cameron said: "He doesn't seem too nervous, but I have to say I'm very glad it's him and not me."

The three-way debates in 2010 saw a boost in the polls for Mr Clegg, although this year's debate is more likely to present an opportunity for one of the smaller party leaders such as Nicola Sturgeon of the SNP or Plaid Cymru's Leanne Wood.

While campaigning at a factory in Huddersfield on Wednesday, Mr Miliband said the debate was a good opportunity to speak directly to Britons.

"The way I'm going to prepare for this debate is by coming to talk to good people here and keep campaigning," he said.

"The thing I value about the debate is the chance to talk directly to the British people, as I am doing today, about the things that matter to me and how I want to change the country," he added.

UKIP's campaign chief Patrick O'Flynn said Nigel Farage is preparing "rigorously" for the event.

"Obviously this will be the only chance he gets to be on the same stage as David Cameron and that's David Cameron's doing, not Nigel Farage's, so that again means that there will be key arguments to put there," Mr O'Flynn said.

Ms Sturgeon described the debate as "historic" and added: "Tonight's debate will hear a real progressive alternative to Westminster cuts.

"The SNP will be a positive and constructive voice, willing and ready to join forces with others in a progressive alliance to end austerity and to protect vital public services like the NHS."

In a video posted on Twitter by the Green Party, Ms Bennett said she was "really looking forward to the debate".

She added: "Finally, the debate about the debates has finished and we can now start talking about the issues."

Ms Wood, who believes her party could hold the balance of power after the election, wrote a message on her Facebook page this morning which said: "Big day for Plaid Cymru today. A big thanks to all for your kind messages."
