Mr Tusk warned last week that Prime Minister Theresa May's plan to leave the single market and customs union made "frictionless" trade impossible.

 

The European Parliament has also stressed that its preferred option is for the UK to continue to be a member of the single market and customs union after Brexit, in a draft resolution, leaked to the Politico website.

 

The parliament does not have a formal role in the Brexit negotiations but does have a veto on the final deal.

 

'Red lines'

The European Parliament document, which may be changed before it is adopted later on Wednesday, says non-EU members - even if very closely aligned to the bloc - cannot expect the same rights and benefits as EU members.

 

It also warns that the UK's current "red lines" in Brexit talks "would lead to customs checks and verification which would affect global supply chains and manufacturing processes, even if tariff barriers can be avoided".

 

It says a "deep and comprehensive" trade deal, of the kind envisioned by Theresa May, must entail "a binding interpretation role" for the European Court of Justice.

 

The European Parliament resolution also warns the UK against "cherry-picking of sectors of the internal market".

 

BBC Brussels Correspondent Adam Fleming said the draft will look like a rejection of the speech Theresa May delivered on Friday setting out her vision of post-Brexit trade, but with some "wriggle room" and the possibility of much more if the UK softens some of its red lines.

 

Verhofstadt wants 100% rights guarantee

European Parliament Brexit chief Guy Verhofstadt met UK ministers in Downing Street on Tuesday for talks on the rights of EU citizens in the EU, and vice versa, after Brexit.

 

The European Parliament is due to vote on the resolution, the fourth it has issued on Brexit, next week.

 

MPs in Westminster are, meanwhile, set to debate a Plaid Cymru call for UK nationals to be allowed to keep their EU citizenship after Brexit.

 

Plaid said EU citizenship would give holders the right to travel, live, study and work anywhere in the EU even after the UK leaves next year.

 

A UK government spokesman said only citizens of EU member states could hold EU citizenship.
