” I seem duty bound to resist it relentlessly from the Labour benches ,” Adonis wrote.” You are engaging a course fraught with danger…If Brexit happens, taking us back into Europe will become the mission of our children’s generation, who will marvel at your acts of demolition .”

Adonis was appointed to the National Infrastructure Commission in 2015 by then Chancellor of the Exchequer George Osborne, to push cross-party consensus over long-term decisions to invest in infrastructure. His deviation and guaranteed to oppose May’s Brexit strategy is another sign that even as Britain leaves the EU, divisions pervade in all areas of the political establishment.

‘Nervous Breakdown’

And now, periods from the end of the year, Adonis is departing with an excoriating verdict on the country’s direction.

” Brexit is causing a nervous breakdown across Whitehall ,” Adonis wrote.” The government is hurtling towards the EU’s emergency exit with no credible plan for the future of British trade and European cooperation, all the while ignoring — beyond sound-bites and insufficient programs — the emergencies of housing, education, the NHS and social and regional inequality which are undermining the fabric of our commonwealth and feeding a populist upsurge .”
