Pressure on May builds as CBI warn remaining in customs union is best option for UK business.

Theresa May is being warned by the head of the CBI that time is running out to make progress on Brexit and remaining in a customs union with Brussels is the best option for British business.

Carolyn Fairbairn, director general of the business organisation, will stress that urgent progress is needed on agreeing a transitional deal with the European Union by the end of March and the framework for the future trading relationship with Brussels must be set out by October.
