A third runway at Heathrow is now uncertain after a Court of Appeal said it was unlawful, bearing in mind the Government's climate change targets. The Department of Transport said the expansion would benefit passengers, boost the economy by up to £61 billion and create 77,000 jobs by 2030. Heathrow's chief executive, John Holland-Kaye, said that more than 40 per cent of the UK's exports to non-EU countries now go through Heathrow. He added that a third runway was vital in order to strengthen international trade links. The airport has also committed to introducing legally-binding environmental targets, including on noise, air quality and carbon emissions. This expansion has been on the cards for years and is vital if our economy is to be truly global now that we have left the EU. MPs voted 4:1 in favour of a third runway not that long ago and I find it extraordinary, and worrying, that, yet again, the courts are interfering with parliament's decision. I am also surprised that the Government is not making more noise about this decision, bearing in mind the reaction to judicial decisions during the Brexit saga. There is talk of expanding regional airports instead, but that simply will not suffice. London is an important business hub and the infrastructure must be there to support it. This is a backward step and I note that Heathrow is going to the Supreme Court, and I hope they win. Off to Dorchester first thing for a regular catch-up with the Leader and officlals from Dorset Council. This is a most useful exercise and allows me and the council to exchange information and keep abreast of what is going on in parliament and in Dorset. Next stop was the Atlantic Academy on Portland, where, in lashing rain, I was met by about eight student leaders, including the headboy, who took me up to meet the Principal and island Mayor, Cllr Sue Cocking. Susan had brokered the idea of a youth council, which the Academy is supporting. Students will vote for 15 of their colleagues to sit on this council, which will represent the school on local issues. It's a great idea and one I support. After being shown around the Academy for 30 minutes, we were led into the auditorium, where about 25 students were seated. There was a question and answer session for about 30 minutes, where I was bombarded with excellent questions, ranging from climate change to my role in parliament. At 1345, I had to leave, regrettably, as I was due at the YOI at 1400. There I was met by Governor Steve Hodson and we spent an hour together chatting through a whole range of matters to do with the prison.
