Sky News and Channel 4 have offered to change the date of their proposed head-to-head debate between David Cameron and Ed Miliband.
It comes after Miliband challenged Cameron twice during prime minister’s questions on Wednesday to commit to the debate due to be broadcast on 30 April.
“I will be there on April 30th, will he be there, yes or no?” asked Miliband.
The Tory leader declined to say if he could appear against his Labour opposite number, saying the time for debate was “before the election campaign”.
In response, Sky News and Channel 4 issued a joint statement saying they “are continuing to prepare for a head-to-head debate between the prime minister and the leader of the opposition on 30 April”.
“However, in response to media inquiries following today’s PMQs, we would obviously be willing to host a debate on a different day the two main party leaders could agree on.”
Two other debates featuring seven party leaders are due on 2 April and 16 April.
After a series of disagreements over who should be invited to the debates, broadcasters published renewed proposals in February. The first two debates would feature the leaders of the Green party, Scottish National party and Plaid Cymru as well as Cameron, Miliband, Nick Clegg, of the Liberal Democrats, and Ukip’s Nigel Farage. The final debate would be a head-to-head between Cameron and Miliband.
