"A Ukip MP believes a Channel 4 docudrama will only boost his party's appeal with voters, as the communications watchdog received more than 700 complaints.
Douglas Carswell said the broadcaster had missed the chance to provide "genuine radicalism" on television with Ukip: The First 100 Days, adding: "We just got Guardian television."
The programme mixed archive footage with imagined scenes, which included the depiction of rioting on the streets in the wake of a Ukip general election victory.
Ofcom said the programme prompted 731 complaints since it was shown last night.

"We will assess these complaints before deciding whether to investigate," an Ofcom spokesman said.
Ukip MEP and parliamentary candidate Gerald Batten called on Ofcom to launch an investigation to establish whether the programme breached the broadcasting code.
But Channel 4 defended the programme, insisting that it was fully in compliance with the code.
Mr Carswell, who became Ukip's first elected MP last October, said: "We are doing a great deal of work in the key seats that Ukip is focused on winning and the Channel 4 mockumentary reinforces the view amongst those voters that we are presided over by a smug, arrogant, out-of-touch commentariat class.
"The mockumentary was supposed to damage Ukip but I think it's reinforced the sense of cultural alienation and I think it makes people more likely to vote for Ukip against the cartel in Westminster.

"Our cultural elites are just not good with politics - they are out of touch with the voters of Britain."
Mr Carswell said he found it interesting that the programme did not focus on Ukip's "success built on credible, liberal policies" demonstrated in recent by-elections.
The Clacton MP said: "It's the most egregious of bias but we have that from the state-funded and state-backed mainstream media every day. We get it from the BBC."
Mr Carswell said he could not imagine a similar programme being made about the Green Party, adding: "The only truth the documentary revealed was the bias of the commentariat class. I think it will magnify Ukip's appeal. We need to get our country back." "
Well that's okay, then, POGS. UKIP only has two MPs, and one of them disagrees with his leader. Doubtless he will change his mind when Farage tells him he has to!
