Triggering Article 50 will plunge the UK into turmoil - and the EU with it. It's mutually assured destruction

The aftershocks of the Brexit earthquake are reverberating throughout the towns of Britain, the boardrooms of corporations and the capitals of Europe. The first casualty has been Prime Minister David Cameron, who has bequeathed the country a divided legacy.
The immediate benefactors are the hard-line Tory eurosceptics and the far right. The anti-Corbyn coup threatens to leave the progressive left virtually moribund.
Waves of xenophobia have been unleashed. Vitriolic tabloids have helped to whip it up. But Cameron's government must bear the bulk of responsibility. They spent six years exploiting anti-migrant rhetoric to divert blame from their austerity policies. These are the real causes of enforced misery and poverty, not immigration.
