As reported by The Daily Telegraph, speculation over a potential new deal in the pound and British stock. Downing Street is believed to be privately shared in Brussels. A senior US diplomat said: "There are elements that will allow the negotiating teams to continue their efforts in search of a positive outcome.

"We hope that we can find a deal by the time of the EU summit."

The compromised could include Northern Ireland.

This move will result in a customs border in the Irish Sea.

Northern Ireland will also be able to benefit from free trade deals negotiated by London.

Prime Minister Boris Johnson said: "Under the circumstances, we will not be able to take advantage of Brexit."

Mr Johnson said he could see a deal, but that does not mean it is a deal.

European Council President Donald Tusk said he saw "promising signals" from Mr Johnson's meeting with Irish Taoiseach Leo Varadkar.

Brexit Secretary Stephen Barclay puts with Michel Barnier, with the latter describing the two-hour discussion as "constructive".

A DUP source said, however, it was not opposed to a post-Brexit customs partnership: "Provided it does not mean that Northern Ireland is excluded from being able to compete, we could be supportive."

Mr Johnson may have to rely on Labor MPs to gain more support for a deal on this compromise.

Remainer MPs are believed to be in favor of a second confirmatory referendum as a prerequisite to the deal.

This could cause another delay of up to six months.

Brexit Party leader Nigel Farage warned against excessive concessions.

Mr Farage said: "Let's hope this is not a surrender."

Tory MP Owen Paterson tweeted: "Northern Ireland being held in the customs union without Great Britain is a breach of the Principle of consent in the Belfast Agreement.

"This would be a problem in Northern Ireland long after Brexit is resolved."

Deputy leader of the DUP Nigel Dodds retweeted him adding: "Absolutely right."
