May: customs backstop to only apply in 'very limited' circumstances

Theresa May has said that her backstop plan to keep Britain aligned to the customs union beyond 2020 would only apply in a “very limited” set of circumstances as Brexiters ratcheted up pressure on her over the future customs relationship.The prime minister said nobody wanted the UK to resort to the option despite persuading her “war cabinet” to sign up to new proposals last week, marking rare progress on Brexit after weeks of deadlock.
