McDemo's, a venture by protesters including comedian and campaigner Mark Thomas, offers proxy demonstrations for people too busy to protest in person.
"Ever wanted to bring capitalism down but can't get time off work to do it?" the company's website asks. "Then McDemo's is for you. We'll force MPs from office while you catch up with Desperate Housewives on E4."
There are two items on the menu. At 99p, the Value Demo includes a 30-second protest in Parliament Square with a slogan on an easy-wipe board held aloft for 30 seconds and accompanied by chanting. For £5, the Happy Demo buys a personalised banner and photo keepsake. Protest songs are extra.
McDemo's aims to help reverse measures included in the Serious Organised Crime and Police Act 2005.
