Labour has accused David Cameron of being frightened of a debate with Ed Miliband, claiming the PM's latest proposal to broadcasters was an attempt to "bully" them.
In a statement following the Conservative leader's "final offer" of a one-off, seven-party debate, the head of Labour's General Election strategy Douglas Alexander said: "We continue to support the broadcasters proposals, including for seven-way debates alongside a two-way debate.
“But this is an outrageous attempt from the Prime Minister to bully the broadcasters into dropping their proposals for a head-to-head debate between David Cameron and Ed Miliband.
“That it comes only hours after Ed Miliband called David Cameron's bluff and said he would debate him any time, any place, shows the lengths David Cameron will go to run scared of a debate with Ed Miliband.”
An Al Qaeda terrorist has been found guilty of plotting to bomb a Manchester shopping centre and the New York subway by a US jury.
Abid Naseer, 28, planned a car bomb attack on the Manchester's Arndale shopping centre on the Easter weekend in 2009.
Had his Manchester plot succeeded, police believe it would have been as big as the 7/7 attacks in London.
The police officer who shot dead an unarmed black 18-year-old in Ferguson, Missouri, will not be prosecuted over the shooting, the US Justice Department has said.
Darren Wilson was cleared by a Missouri grand jury in November over the death of Michael Brown, which sparked huge protests across the country, before resigning from the department.
Federal officials concluded there was no evidence to disprove Mr Wilson's testimony that he feared for his safety.
The officials also said there was not reliable evidence that Mr Brown had his hands up when he was shot last August.
A third man has been arrested on suspicion of money laundering by police investigating large-scale fraud linked to extremists travelling to Syria.
The Metropolitan Police say that a 37-year-old man was arrested at an address in west London this evening.
Earlier today, two men, aged 23 and 29, were arrested at addresses in west and east London.
Scotland Yard said the arrests are linked to reports of vulnerable and elderly victims being "cold called" over the phone by a suspect impersonating a police officer, who informs them their bank account has been compromised.
Victims are then tricked into transferring money to an account under the control of the suspect, with one elderly victim losing around £150,000.
