Theresa May must push for even softer Brexit, says thinktank

Prime minister urged to offer more concessions to EU to minimise economic damage

Theresa May will be forced to offer further politically difficult concessions to the EU to minimise damage to the economy caused by Brexit, said one of the UK's leading economic thinktanks.

The National Institute for Economic and Social Research (NIESR) said Britain was gripped by an epidemic of uncertainty about the terms of its EU departure, and warned that the government would have to pay a bigger financial contribution or accept higher migration to get the deal it wanted.
