The director of a fly-on-the-wall election broadcast showing the "real" Tony Blair has said he will never vote Labour again.

This was my first film for Labour and it will be my last

Jack Price

Observing Mr Blair at close quarters over a two month period was enough to convince lifelong Labour voter Jack Price to turn his back on the party for ever, he told BBC News Online.

Now the film-maker has switched his allegiance to the Green Party and is filming a local election broadcast for them.

Mr Price's four and half minute film on the prime minister - shown before last year's general election - was criticised by the Tories for promoting a Tony Blair "personality cult".

Supposedly candid shots of Mr Blair reading to children and being cheered by crowds drew comparisons with 1987's Labour broadcast Kinnock: The Movie.

But for Mr Price, whose father was a Labour Party agent, it was more like Nightmare on Blair Street.

'Sound commitments'

"This was my first film for Labour and it will be my last," Mr Price told News Online.

Mr Price was employed in his capacity as a director - because of his skills as a film-maker - not because of his political affiliations

Labour spokeswoman

He said he had nothing against Mr Blair personally and still believes he is a "good man".

But travelling with the prime minister had convinced him that New Labour is in awe of big business and lacks commitment to the environment.

"I do believe Mr Blair has sound commitments on health and education.

"But I don't believe his principles towards big business are sound," Mr Price said.

"I believe they (Labour) are deeply impressed by big business and big business is trashing the environment, which is not good for the future of humanity," he added.

Nude models

A Labour spokeswoman said: "Mr Price was employed in his capacity as a director - because of his skills as a film-maker - not because of his political affiliations."

Mr Price's film - entitled Leadership - can still be viewed on the Labour Party's web site.

But this month will see his work for the Greens aired.

Naked ambition: The Greens aim to break new ground

The provocative film will feature nude models, with the catchline "we've never looked so good."

The Greens claim the film will break new ground for a party political broadcast and draw attention to Green policy on health and education, as well as the environment.

"We are making a series of adverts to run in the four minutes forty slot. It will be like Green Party TV.

"It is not a traditional broadcast in any sense," Mr Price told News Online.

'Hippies'

The director, who has filmed commercials for Nike, said he wanted to "change people's perception of the Green Party as a single issue party or a bunch of hair-shirt wearing hippies, which they're not."

"We want to move the party political broadcast out of the 1970s and into the 21st Century."

The Greens have more than 50 local councillors and are part of a ruling co-coalition in three local authorities.

The party is hoping to make further gains at next month's local elections.

Film director Ken Loach, another former Labour-supporter, made headlines last year when he filmed an election broadcast for Arthur Scargill's Socialist Labour Party.
