The Norwegian Unionist Democratic Party (DUP), British Government partner, has reiterated its opposition to the agreement reached by London and Brussels on the United Kingdom's departure from the European Union (EU).

Shortly after the British Prime Minister Boris Johnson and the European Commission (EU) confirmed the existence of a pact on the "brexit", fDUP sources told the British BBC and the Irish RTE that their position remains the same.

"Our previous statement is still standing, in response to the news that an agreement has been reached," says the DUP note, whose ten deputies in Westminster allow Johnson to rule in the minority and whose votes are key to ratify the new agreement.

The leader of the DUP, Arlene Foster, had issued the statement expressing reservations regarding the agreement. The border between the two Irlandas is the most complicated matter in the agreement on 'brexit', since the objective is to avoid establishing a border infrastructure so as not to harm the peace process of the British province.

The conservative prime minister, having no parliamentary majority, needs the support of the DUP if he wants to ensure that the agreement with Brussels can be approved by the House of Commons of the Westminster Parliament.

"We've participated in continuous conversations with the Government. As things stand, we could not accept what is being suggested about customs and other issues about consent, and there is a lack of clarity about VAT, "the note emphasizes.

However, the statement, signed by Foster and the "number two" of the formation, Nigel Dodds, said that "they will continue working with the Government to try to obtain a sensible agreement that works for Northern Ireland and can protect economic integrity and constitutional of the United Kingdom ".

In recent days, Johnson had intense negotiations with Foster to find a way to overcome the most difficult points, although the details of what is negotiated have not been disclosed.

According to what has transpired, in the agreement with Brussels, it is expected that Northern Ireland remain aligned with certain European single market rules but be part of the customs territory of the United Kingdom, with which the controls to the goods will be carried out at the point of entry into this British territory and not in the Republic of Ireland.

As explained by the EU chief negotiator for Brexit, Michel Barnier, at a press conference, the UK authorities will be responsible for applying the European Union customs rules in Northern Ireland.
