An hour before Channel 4 broadcast last night's mock fly-on-the-wall documentary about Ukip, the party’s leader Nigel Farage blamed the programme’s “monstrous aspersions” on fear.

The fictional dystopian piece, named Ukip: The First 100 Days, aimed to give the viewers a pre-election 'insight' into how the country would be run under a Ukip government.

It was aired from 9pm - 90 minutes after Mr Farage hosted a meeting for voters in his hopeful constituency town of Sandwich.

“There’s a reason why Labour and Conservatives are being so rude,” he said.

“It’s because they are scared of us. It’s because we have shaken up the political path and don’t they know it?”

“It’s because they are scared of us. It’s because we have shaken up the political path and don’t they know it?” Nigel Farage, Ukip

He referred to the “purple rash” of Ukip that has put the prime minister’s pledge for a Europe referendum under the spotlight.

Mr Farage said the party’s pressure has forced David Cameron to honour his promise.

Channel 4’s programme featured Priyanga Burford as Deepa Kaur, Ukip’s newly elected fictional MP for Romford.

It alluded to ex-military personnel carrying out raids on the homes of illegal immigrants, being heavy handed and injuring a 14 year-old boy.

It resulted in the fictional Deepa publicly announcing that the actions were "un British" and people were squaring up to each other in the streets 100 days on from the Ukip election victory.

Despite being billed as ground-breaking and provocative, the What If show has been slammed as “unconvincing” in the Guardian and “fatally flawed” in the Telegraph.

Ben Lawrence, writing for the latter, said he found it surprising that the “gift to dramatics” that is Mr Farage, was reduced to a walk on part when he would have been the country’s prime minister.

As he wound down the meeting, and prior to watching the show, Mr Farage told the gathering of 180 people: “I’m a realist. I’m not going to be become prime minister on May 8”.
