Climate activists get frosty with the glam face of Plane Stupid

She became the glamorous face of the green movement through her protests against airport expansion.

But Tamsin Omond has now split from the climate change organisation that made her name.

Anti-airport expansion group Plane Stupid admitted she is no longer active with them. Insiders said some protesters are unhappy over comments she has made about the green movement.

It is claimed Miss Omond, 25, was shunned by other activists after a series of rows at recent climate change meetings. One source said: "She has alienated many members of Plane Stupid and will not be welcomed or invited to events."

Miss Omond, granddaughter of baronet Sir Thomas Lees, was arrested last year after climbing on to the Palace of Westminster roof and unfurling a Plane Stupid protest banner.

She once chained herself to the gates of Biggin Hill airport. But she recently said: "I know the green brand is unwashed, unshaven and up a tree. That doesn't represent me." She told activists to grow up.

Miss Omond set up her own group, Climate Rush, after failing to get a full-time job as Plane Stupid's national coordinator.

Then last year she led the group and 1,000 activists in a rush on Parliament. This summer the group dumped a bucket of manure on Top Gear presenter Jeremy Clarkson's driveway, provoking ridicule from hard-core activists. One said: "It was like the Famous Five go camping."

Leo Murray of Plane Stupid said: "Tamsin is not busy with us because she has her own mission and we are very supportive of that. There is no acrimony between us."
