"We're prepared to have great transparency on all the negotiating documents that are to be made public", the European Union's chief Brexit negotiator, Michel Barnier, told lawmakers on Wednesday at the European Parliament in Strasbourg, France.
The guidelines agreed by the Council are broadly in line with the key principles and conditions for the UK's withdrawal agreement European Parliament adopted on 5 April.
In line with negotiator Michel Barnier, most MEPs emphasised the unity between the European Union institutions and the 27 Member States, who are determined to act together to reach a balanced agreement with the United Kingdom.
Most European governments say preserving the integrity of the EU is their priority in the negotiations, but some economists and businesses have urged efforts to avoid a precipitous exit.
"In fact, I very much appreciate on the United Kingdom side you could find the same spirit to reach a deal with the European Union, not against the European Union".
Mr. Barnier said many people regretted Britain's decision to leave, "but now we have to implement it and that decision has consequences".More news: It's Honda's problem, not mine, says Fernando Alonso
Mainstream British media said May would pitch immigration strictures and trim certain welfare benefits for pensioners when she unveiled her pledges later Thursday for Britain's snap June 8 election.
The newspaper said the advisory council had warned there was little chance of a sufficiently deep agreement being concluded by the planned 2019 exit date.
With just over a month to go before negotiations are due to start, the bloc set out how it will make its negotiating documents public every step of the way. "That won't work. At that point, we'll have to think about which restrictions we do on the European side to compensate for that".
Prime Minister Theresa May has committed to ending the right of free movement for European Union citizens coming to the United Kingdom after Brexit, and the Conservatives' general election manifesto will reportedly include a pledge to slash immigration dramatically. Mr. Juncker went further with a comment saying that he would speak French as English is clearly losing its importance in the continent. "I doubt it, because in any part of the civilized world frankly that behavior would be considered to be bloody rude and the act of a bully".
"Well, I'll tell you something, your attempt to bully the Brits through this negotiation is not working - 68% now of the British people want Brexit to happen".
The MEP said: "Either we get some grown-up, reasonable demands from the European Union or the United Kingdom will be forced to walk away before the end of this year. We can't spend two years with this farce".
