The Italian MEP made a series of barbed remarks about splits within the prime minister’s Cabinet and also defended his decision to meet with the Labour leader Jeremy Corbyn.
He said progress on the divorce so far “has not been satisfactory” and warned the UK it will have to accept current membership terms during any transition only without representation.
Mr Tajani made the remarks during a press conference at the EU Council summit in Brussels, where the 27 leaders are tomorrow set to rule that the talks cannot move onto trade yet.
The parliament president almost brushed over Brexit completely in his opening remarks, and appeared irritated to be asked so many questions about Britain’s impending exit from the bloc.
Grilled on MEPs role in the talks, he said they are “fully involved in all the initiatives” related to the negotiations and insisted they will veto any deal that does not meet their red lines on citizens’ rights.
Mr Tajani said: “The progress so far has not been satisfactory. We heard the tone of the speech by Mrs May but I”m still waiting to see the tone of that speech, the more flexible approach, I’m waiting to see that transformed into practical deeds.
“Basically we’re not satisfied with the result so far. We very much hope we will get an agreement in the future. The EU is united, the institutions and the Member States we all have the same vision of things.
“There’s maybe a lack of vision within the UK as to what they want to do but not within the EU. we don’t have differing positions within the EU we all view this in exactly the same way.”
The Italian was also asked whether or not he feels the bloc’s hardline stance on sufficient progress risks further weakening Mrs May’s precarious position and making the talks even harder.
He replied: “The question you put depends on the UK I can’t decide who will be the British prime minister but who that will be over the coming months and years it’s not up to me to say.”
His remarks came after a now infamous BBC interview earlier this week in which he raged that Mrs May’s offer to cover £18 billion of EU budget liabilities amounted to “peanuts”.
One EU source told express.co.uk that Mr Tajani is angered by the fact that the parliament’s Brexit coordinator, Guy Verhofstadt, is receiving more press coverage than him despite the fact he is its president.
The former Belgian PM has become a high-profile figure due to Brexit, appearing in newspapers and on the airwaves across the continent in his role representing MEPs’ interests.
The EU parliament has no official role in the negotiation although it will get a veto on the final deal. However, MEPs will only be able to block the entire deal and not alter individual parts of it.
On the parliament’s role, Tory MEP Syed Kamall explained: “The only thing it’s got is the right to veto at the end. It agrees to the agreement or it disagrees to the agreement.
“The Parliament is not the negotiator. It doesn’t have a formal role in the negotiations, so by having all these resolutions and these committees it can try and make itself relevant.”
