Political Times: The TV debate row, Ukip's immigration plan and Nick Clegg on drugs

The issue of TV debates ahead of the general election has reignited after Ed Miliband pressed David Cameron on the matter.

The Tory leader previously said he would only take part in them before the general election campaign official begins.

But Cameron, after an exchange with the Labour leader during Prime Minister's Questions, issued an ultimatum to the broadcasters.

He will only take part in one 90-minute long debate and it would have to include all seven party leaders, ruling out a head-to-head between him and Miliband.

After news of Cameron's latest demand broke, the reactions from across the political spectrum came firing in.

Nick Clegg, his Coalition Government partner, accused the prime minister of holding Sky, Channel 4, the BBC and ITV "to ransom".

Labour spin doctor Alistair Campbell went further. He said Cameron was a coward for not agreeing to the broadcasters' latest plan.

Ukip's immigration plan

Elsewhere, Ukip launched their Australian-style immigration plan.

The party said it would not have an "arbitrary" target after mooting a 50,000 people cap earlier in the year. Nigel Farage stressed that the proposal was "positive" and "normal".

Ukip also said it would hire an extra 2,500 border staff and set up a new quango designed to cut net migration to the UK, called the Migration Control Commission.

Farage claimed the plan was a "common sense solution". We will only have to wait until May to see if the voters agree.

Nick Clegg's drug policy

Finally, the Liberal Democrats announced that they would move drug policy from the Home Office to the Department of Health.

Nick Clegg said that some of the current laws are "ludicrous" because teenagers have to declare that they have committed a drug offense, if caught, years after the act.

Clegg, in a bid to win over young voters, argued that this unfairly puts their future job prospects at risk.
