Yes, I wish My Lord Lawson every success, even though he has his work cut out.
As youngmaf says, no meaningful reforms will be secured. The best that can be hoped for is a bit of cosmetic tinkering around the edges and any changes will either be “promised” by 2030 (and quietly forgotten by then because those who agreed to the changes will be either dead or drawing their platinum-plated EU pensions) or made and then quietly reversed without much ado. This is the way the EU operates and there is no way on earth that agreement will be reached to address the fundamental problems of the bloc such as the free movement of people, the single currency (which does influence the UK even though we are not a participant), the supremacy of EU law and the move towards “ever closer union”.
Interestingly a number of major business leaders have quietly changed their tack over the past few months. Most of them said previously that a Brexit would be an absolute disaster. Now more of them are veering towards neutral, some say it will make little or no difference and others positively welcoming the chance for the UK to be “consciously uncoupled” from the over-regulated, undemocratic, corrupt and moribund organisation that the EU has become.
Strangely the only leading figure to have changed his mind in the other direction recently is one Jeremy Corbyn. He was staunchly in favour of a UK departure until he realised he may be in a position to exert some influence. Just whether and by whom he has been got at is a mystery, but his stance changed with a week or two of being elected leader of Her Majesty’s Loyal Opposition. It's a funny old world.
