In a “deeply cynical” move MEPs have put forward the motion apparently aimed at wrecking progress on talks.
The debate next week has also been timed to coincide with the Conservative conference so many British eurosceptic MEPs will be away to defend the UK’s reputation.
Tory MEP David Campbell Bannerman, a leading Brexit campaigner, blamed the European Parliament’s Brexit negotiator Guy Verhofstadt for the attack.
He said: “I have always been convinced that Verhofstadt is a wrecker who wants to wreck the talks so he can recommend that the European Parliament rejects the final outcome of the talks.”
He pointed out that the motion was not binding but was aimed at damaging the reputation of the UK Government.
He said: “This is another example of them holding a debate on the UK during the Conservative conference in a deeply cynical move which shows contempt for Britain.
“Obviously they want the Tory MEPs to be away so we cannot defend Brexit and the UK talks.”
He added: “It just shows that the sooner we are rid of this lot the better.”
The motion says that the European Council should determine that “sufficient progress” has not been made on the EU’s three key aims of safeguarding EU and UK citizens’ rights, clarifying the UK’s financial commitments and resolving the Republic of Ireland/ Northern Ireland border.
MEPs are then set to back the call for the talks to not progress onto the vital issue of trade threatening to force the UK to walk out of the discussions and businesses across the EU to be impoverished by a breakdown of trade.
The move comes despite an acknowledgement that Theresa May’s speech in Florence was “constructive” and has significantly moved the issues forward.
No reciprocal attempt to find agreement has been made by the EU.
And in a further blow to those who want the talks to progress European Council President Donald Tusk has blocked Brexit talks at the next summit of government leaders in Tallin.
Instead the heads of government will be attending a Sting concert.
Explaining his recommendation Mr Verhofstadt said: “Prime Minister May opened the door to progress in her speech in Florence on September 22, for example on the role of the European Court of Justice.
“But we would like to see the UK government provide greater clarity. We are still waiting for answers on vital issues, such as how to keep Northern Ireland in the customs union, or how to find a special arrangement that will prevent a hardening of the border.
“Regarding citizens’ rights and the financial settlement, we are waiting for concrete answers to the proposals made by the EU negotiating team.”
