UPDATE: Lord Peter Mandelson, the unelected Secretary of State for Business, Enterprise and Regulatory Reform and key player in the Heathrow expansion plan, attacked with green custard.

Plane Stupid Scotland activists shut down Aberdeen airport by setting up a golf course on the taxiway and surrounding themselves with security fencing whilst another group occupied the roof of the terminal with a banner reading, “Nae Trump Games with Climate Change”. The 3am action prevented the scheduled reopening of the runway at 5am. After almost six hours the protesters voluntarily unlocked themselves when police claimed the taxiway was needed by an emergency helicopter. Eleven people, including local residents, were arrested.

Donald Trump backs Aberdeen airports expansion (where his super-rich pals will arrive to play golf on his controversial golf course). BAA obviously welcome Trump's involvement and need powerful friends right now. They are under presure from the Competition Commision and a down turn in the aviation industry is threatening expansion plans. Plans for a new runway at Stansted (blockaded by Plane Stupid last December) now looks likely to be postponed for at least two years and the airport will be put on the market without planning permission in place.

Despite government rhetoric about cutting CO2 emissions, there are expansion plans for 34 regional airports in the UK. Last month Plane Stupid activists interrupted a public meeting during a speech by Ed Miliband the Secretary of State for Energy and Climate Change, unveiling a banner highlighting the hypocritical actions of the government in relation to aviation and climate change. Back in January Plane Stupid activists chained themselves to the entrance of Southampton airport and erected tents at the main entrance in a bid turn the regional airport into a climate refugee camp (they were in court yesterday and fined between £175 and £600 each).
