Politicians may do a decent job of making themselves look silly, particularly at election time when there are plenty of screaming babies to hug and uppity farmers to punch, but Rory Bremner will be taking his opportunity to have a laugh at their expenses as he hits the road for his Election Battlebus tour.

Bremner will be performing sold out shows at Ealing’s Questors Theatre on Monday and Richmond Theatre on the following Sunday. According to the impressionist, the evenings will be “part comedy show, part town-hall meeting” as he will perform a set of topical stand-up followed by a question and answer session featuring a panel of invited guests.

The Questors audience will get a chance to grill Ealing North’s Labour MP Steve Pound and political commentator John Kampfner but it is at the show in Richmond where sparks could really fly as Susan Kramer goes head-to-head with her rival for the Richmond Park seat, Zac Goldsmith.

The Richmond audience will also be treated to an appearance from Bremner’s regular collaborators John Bird and John Fortune and he is excited to see how the tour pans out.

“Obviously there will be the stand-up comedy but in the run up to the election we wanted to have something different,” he explains.

“It will be like Bremner, Bird and Fortune meets Question Time. I know from doing book festivals that audiences like to participate and I love the atmosphere that comes from people getting involved.”

Bremner says he may well be doing some familiar impressions in the stand-up section of his show - is that a reflection of the lack of characters at work in our current political system?

“ [Spitting Image producer] John Lloyd is of the view that is down to the caricaturist to find the key to the characters but it does seem to me that it is slightly more difficult than it has been in the past,” he replies.

“Most people have acknowledged that if I did five minutes of David Milliband it would kill people so there will be quite a bit of David Blunkett, Michael Howard and John Prescott. In many ways it will be the last time we see those characters - Michael Howard will go off into the twilight!”

Bremner has always been guarded about who he votes for and he says he is “disillusioned” this time around, yet he also admits to feeling a tad sorry for Gordon Brown, who he says doesn’t always get the credit he deserves.

If you were a betting man though you could safely wager against Bremner backing the Conservatives, if his views on David Cameron are anything to go by.

“I’m not that convinced by him at the moment” he says. “I get the impression he is like Blair, sitting around shooting the breeze with a few advisors, and I think he is everything we think of as a modern politician, confident and fluent but I don’t see the solidity.”
