The EU will threaten to “stall” the Brexit talks if the UK does not make a serious offer on the so-called “Brexit bill”.

The move is the latest attempt by the European Commission to browbeat a €100bn financial settlement from the UK as a price of leaving the EU in March 2019.

It emerged on the second day of Brexit negotiations in Brussels where 98 British officials are facing off against their 45 EU counterparts in a bit to reach a deal on questions surrounding the rights of EU and UK expats after Brexit, Northern Ireland and the financial package.
