The EU has produced a third Brexit document to accompany the two already published that set out the terms of Britain's departure from the bloc and the future relationship between the two sides.

The third document, obtained by POLITICO, is currently titled the "draft statement to the minutes" of Sunday's European Council meeting of the other 27 leaders of the EU. Little more than a single page, it sets out some elements of how the EU plans to implement the Brexit deal and to pursue negotiations on the future relationship.

The text touches on several key issues including the importance of a level playing field in competition and access to U.K. fisheries. These are issues on which some EU countries feel the text of the Political Declaration document published on Thursday does not go far enough. That 26-page document sets out the framework for future relations between the EU and U.K.

The document also says the European Council will “continue to provide the necessary political direction” in respect of the implementation of the Withdrawal Agreement, the 585-page divorce deal agreed earlier this month.

On the sensitive issue of fisheries, the text underlines that an agreement is a “matter of priority,” and should build on “existing reciprocal access and quota shares” — a demand that several countries including France pushed for. Such an agreement “should be negotiated well before the end of the transition period.”

Finally, the text makes clear that any decision on extending the transition period — currently foreseen to end in December 2020 — “will take into account the fulfillment of obligations by the U.K.”

A meeting in Brussels of advisers to EU27 leaders that was convened to put finishing touches to the Brexit deal broke up without agreement on the issue of Gibraltar, according to two EU diplomats.

Spain has raised serious objections in the last few days over over the text of the declaration and the 585-page Withdrawal Agreement over its treatment of Gibraltar. It wants the text to make clear that future talks with the U.K. are separate to those regarding Gibraltar — and Spain has a say in how those proceed.

"Spain is seeking a clear declaration from the U.K. that they recognize the EU interpretation of the geographical application of Article 184 of the Withdrawal Agreement [which deals with negotiations over the U.K.'s future relationship with the EU]," Luis Marco Aguiriano, the secretary of state for the EU, told POLITICO.

One EU diplomat said the Gibraltar question was dealt with at the meeting of EU sherpas, but was not the main topic of conversation. Another diplomat said Spain is "very worried" about the potential legal misinterpretation of Article 184 in the Withdrawal Agreement in the way it is currently drafted.

Two diplomats said that the issue is now being handled bilaterally between the U.K. and Spain, but there is so far still no agreement.
