A key member of the European Parliament’s Brexit team has described the manner in which the UK is conducting the Brexit negotiations as “a shambles” and warned that Michel Barnier is privately expressing his concerns, The Independent can reveal.

Belgian MEP Philippe Lamberts, who sits on the influential cross-party Brexit steering group, said he had never witnessed such “unpreparedness, lack of professionalism and competence” from politicians and that UK negotiators have “no direction” due to a lack of clarity from the government.

Theresa May is meeting with her cabinet at Chequers on 22 February to address this issue and is looking to produce a coherent plan for the UK’s future relationship with the European Union.

The government has been split for months over how the negotiations should proceed and the summit is when the cabinet will be forced into finally agreeing on a position.

Mr Lamberts, who meets with Mr Barnier on regular basis, said that the chief negotiator was concerned with the UK’s current demands.

“I talked with him [Michel Barnier] in a private meeting and yes we are worried. He may speak less bluntly than I do but he is quite clear. We are worried. What we see on the other side of the channel is a shambles,” he told The Independent.

Brexit: Britain asks EU to consider longer transition period

Discussing Ms May’s recent Brexit announcements, Mr Lamberts, said that her messages had been “mixed at best” and were a series of contradictions.

“I would not like to be a British civil servant or negotiator because I wouldn’t know what to do because I have no direction,” he added.

Ms May’s hopes of finally producing a detailed plan on Britain’s future relationship with the EU rests on whether there will be any reconciliation with the Remain-backing ministers, who are pushing for close regulatory alignment with Europe, and the Leave-backing cabinet members, who are hoping for a much harder Brexit.

David Davis claimed there would be “no final answer” when he was quizzed on the Chequers meeting.

The Brexit Secretary added that the government’s Brexit position would be refined and he joked that Ms May would not let them leave the meeting until they reached an agreement.

“We have started back at Lancaster House with the grand outline of the plan which was the same as it is now in outline,” Mr Davis said.

“That was fleshed out in more detail in Florence. There are two white papers on it. There are 14 policy papers last year - I lazily gave up my holiday all summer to sign them all off.

“And of course we will be talking about some of these specific issues on Thursday. The policy will get more and more and more closely refined and that is what will happen this Thursday and very successfully,” he added.

PA The biggest issues facing UK on leaving EU Customs union A key point in the negotiations remains Britain's access to, or withdrawal from, the EU customs union. Since the referendum there has been hot debate over the meaning of Brexit: would it entail a full withdrawal from the existing agreement, known as hard Brexit, or the soft version in which we would remain part of a common customs area for most goods, as Turkey does? No 10 has so far insisted that “Brexit means Brexit” and that Britain will be leaving the customs union, but may be inclined to change its position once the potential risks to the UK’s economic outlook become clearer. Alamy The biggest issues facing UK on leaving EU Northern Ireland-Irish border Though progress was made last year, there has still been no solid agreement on whether there should be a hard border between Northern Ireland and the Republic of Ireland. To ensure borderless travel on the island, the countries must be in regulatory alignment and therefore adhere to the same rules as the customs union. In December, the Conservative Party’s coalition partners, the DUP, refused a draft agreement that would place the UK/EU border in the Irish Sea due to its potential to undermine the union. May has promised that would not be the case and has suggested that a “specific solution” would need to be found. Getty The biggest issues facing UK on leaving EU Transition period Despite protests from a small number of Conservative MPs, the Government and the EU are largely in agreement that a transitional period is needed after Brexit. The talks, however, have reached an impasse. Though May has agreed that the UK will continue to contribute to the EU budget until 2021, the PM wants to be able to select which laws made during this time the UK will have to adhere to. Chief negotiator Michel Barnier has said the UK must adopt all of the laws passed during the transition, without any input from British ministers or MEPs.

May insists that those who arrive during the transition period should not be allowed to stay, whereas the EU believe the cut-off point should be later.

Infighting within the Cabinet has prevented a solid position from being reached, with some MPs content that "no deal is better than a bad deal" while others rally behind single market access. The EU has already confirmed that access to the single market would be impossible without the UK remaining in the customs union.

However the UK cannot make trade agreements with another country while it is still a member of the EU, and the potential loss of trade with the world's major powers is a source of anxiety for the PM. The EU has said the UK cannot secure trade deals during the transition period.

The comments come as the Dutch government activated a “hard Brexit” contingency plan citing the lack of a coherent message from the UK as the reason why.

The country’s finance minister, Menno Snel, said the event of a “no deal Brexit” was now “conceivable”, Sky News reported.

"The divisions within the British Conservative Party and the remaining lack of clarity about the British input continue to impede the smooth running of the negotiations,” Mr Snel said.
