THIRTEEN climate campaigners who blocked a Heathrow runway in protest at the airport’s planned expansion were spared jail yesterday.

The environmental activists had been found guilty in January of aggravated trespass, after entering a security-restricted area of Britain’s largest airport last summer.

Graham Thompson, Danielle Paffard, Rebecca Sanderson, Richard Hawkins, Kara Moses, Ella Gilbert, Melanie Strickland, Sheila Menon, Cameron Kaye, Edward Thacker, Alastair Tamlit, Sam Sender and Robert Basto were each given a six-week sentence suspended for 12 months.
