Heathrow 13: I'm terrified at the thought of prison, but have no regret

As she prepares for sentencing, one of the third runway protesters says breaking the law will have been worthwhile

Who owns sensible trousers that aren't navy blue or black? In an effort to better distinguish between the guards and the guarded, the prison dress code has ruled out most of my wardrobe. I'm left staring at a sizeable collection of brightly coloured leggings and weighing them against advice from sites like "first time in prison dot com" to "keep your head down".

After a short trial, the so-called Heathrow 13, of which I am one, were found guilty of aggravated trespass and being "unlawfully airside" at the airport for protesting against re-emerging plans to build a third runway at Heathrow. Our sentencing is on Wednesday, and we've been told to "expect custodials".
