Liberal Democrat MEPs have written to JC Juncker after his @SophyRidgeSky interview, to challenge his statement that "Brexit will happen". LD say Boris Johnson lacks a clear democratic mandate to negotiate Brexit on behalf of the UK. Points to LD policy on revoking A50. 
Lib Dems to Juncker: "Please do not fall into the trap of thinking that compromising with Boris Johnson now will in any way 'solve' the British relationship with Europe."
Lib Dem letter points to what many in EU fear: if the UK revokes or remains, the poisonous divisions of Brexit will not heal and will continue to disrupt the EU.
