Chemistry teacher Jamshed Javeed, who wanted to travel to Syria to fight with Islamic State, has been jailed for six years.
David Cameron has denied putting obstacles in the way of televised leaders' debates, saying he has "unblocked the log jam" created by broadcasters.
"I am unblocking the log jam and saying let's have this seven-cornered debate and get on with it before the campaign," the Prime Minister said.
"Then we can actually do what needs to be done, which is to get round the country during the election campaign."
He insisted, "Everyone knows what the Conservative proposals are and the Labour proposals are, and the other parties can speak for themselves."

Nigel Farage has accused the Prime Minister of sabotaging the TV leaders' debates.
Speaking on ITV's Loose Women, the Ukip leader agreed David Cameron was "running scared," telling the panel, "He's sabotaged the whole thing".
"He's now said he'll do one debate, but he'll do it before the proper campaign starts,so it's not going to be a proper debate, " Farage said.
"Had it been a four-headed debate, there were one or two conversations I wanted to have with the Prime Minister that I don't think he would have been answer, and I suspect that's why they've sabotaged."
William Hague has claimed Ed Miliband is only calling for a television debate with David Cameron out of desperation to stop the election slipping away from him.
The Commons leader faced down MPs' anger over the Prime Minister's "indefensible" and "craven" refusal to debate one on one with the Labour leader, stressing that former prime minister Tony Blair refused to do so altogether.
Hague hit back, "I think, of what the leader of the Opposition was saying yesterday when he was calling for a debate, which means 'I am desperate because the election is slipping away from me and I have nothing else to ask about at all'. That is the translation of that."
Sentencing chemistry teacher Jamshed Javeed to six years in prison for Syria-terror related offences, Judge Michael Topolski said he believed the 30-year-old presented a "potential danger" to the British public and had not rejected Islamic State's ideology.
Mr Javeed's father earlier dismissed suggestions his son was a violent extremist who posed a threat to the UK.
Jamshed Javeed appeared to be "just a normal family man" before he was radicalised and wanted to fight for Islamic State in Syria, police say.
Detective Chief Superintendent Tony Mole, the head of the North West Counter Terrorism Unit, said: "He appeared to be just a normal family man with a stable family; he came from a stable background; he was a school teacher and had his own children."
Mr Mole said it appeared the chemistry teacher had become radicalised in "a fairly short period of time" after interacting with a group who were determined to fight for IS.
David Cameron has blamed broadcasters for the row surrounding the political leaders TV debates.
The Prime Minister said: "We're now short of time because of the mess, frankly, the broadcasters have made of this."
He added he was happy to take part in one debate before March 30 but wanted to "do what actually needs to be done and get on with the election campaign".
