Gibraltar is in talks with Scotland about a plan to keep parts of the UK in the EU, BBC Newsnight has learned.
Fabian Picardo, the territory's chief minister, said he was speaking to Scotland's First Minister Nicola Sturgeon about various options. Northern Ireland could also potentially be included in the talks.
The German Chancellor, Angela Merkel, has said there can be no talks on Brexit before the UK formally begins the process of leaving the EU.
While accepting the UK needed time, she added it should not be a "long time".

Scotland's First Minister Nicola Sturgeon has accused Boris Johnson of being responsible for the start of "Project Farce" as the fallout continues from last week's Brexit vote.
She was responding to Mr Johnson stating that "Project Fear was over" - a reference to the supposed "scare tactics" used by the Remain side.
First Minister Arlene Foster says leaving the EU offers new opportunities and she criticises Remain supporters for "prophecies of doom".
Mrs Foster campaigned for a Leave vote in last week's EU referendum.
David Cameron says he doesn't believe the rules set out in the Good Friday Agreement have been triggered to enable a border poll on the reunification of Ireland.
Mr Cameron was responding to a question in the House of Commons from East Belfast MP Gavin Robinson. Sinn Féin had made the call for the border poll following the EU referendum result.
UK financial markets remain volatile in the wake of the Brexit vote, with sterling plunging to a 31-year low against the dollar, and some share trading temporarily halted.
Yields on 10-year government bonds sank below 1% for the first time.
David Cameron says the government has a "fundamental responsibility to bring our country together" in the aftermath of the EU referendum.
Mr Cameron said negotiating an exit would be the civil service's most complex and important task for decades. Labour's Jeremy Corbyn warned his own party - and the Conservatives - against "internal factional manoeuvring".
BBC News NI Political Correspondent Stephen Walker looks at the new shadow Northern Ireland secretary Dave Anderson.
Mr Anderson replaces Vernon Coaker, who resigned in protest at Jeremy Corbyn's leadership.
Irish Foreign Affairs minister Charlie Flanagan says there has been a spike in interest in Irish passports since the UK voted to leave the EU, but warns an "unnecessary surge in applications" would place "significant pressure" on the system.
"The increased interest clearly points to a sense of concern among some UK passport holders that the rights they enjoy as EU citizens are about to abruptly end," he said. "I want to state clearly that this is not the case."
David Cameron says the devolved administrations in Northern Ireland, Scotland and Wales will be fully involved in the negotiations which follow the UK's decision to leave the EU.
Mr Cameron said all key decisions would have to await for the arrival of new prime minister but "a lot of work" can begin now.
From Project Blimey This Is Scary, welcome to Project Reassure - the fundamentals, George Osborne insisted, have not changed.
The chancellor has been tasked with being the lead member of the continuity club, and that will mean him juggling his own daggers.

Just as the Chancellor spent the morning trying to calm the City, so there will be a need to manage the expectations of the country.
Real politics will inevitably mean concession and compromise after a campaign in which both sides seemed at times to suggest it was a choice between Utopia and Armageddon.
DUP MP Gregory Campbell says nobody knows how much the NHS will benefit as a result of the UK's withdrawal from the EU, in spite of his party supporting a claim that it would receive an extra £350m a week.
DUP members erected posters in Northern Ireland bearing that claim, but Mr Campbell now tells the Stephen Nolan Show: "That's not what was said. In two-and-a-half years' time, we don't know what the budget will be."
A post office in Armagh says it's had an unprecedented demand for applications for Irish passports since the result of the EU referendum was announced.
"We handed out approximately 400 forms [on Friday], which is unheard of here," owner Gavin Emerson adds."We have never handed out more forms in such a space of time ever before."

The fallout from the biggest exercise in popular democracy has already been dramatic - claiming the scalp of a prime minister and, potentially, that of the opposition leader too.
It has, though, only just begun.
An online petition calling for a second EU referendum has been hijacked by automated bots adding false signatures.
Thousands of names appeared to have come from people in Vatican City and Antarctica, and the House of Commons petitions committee says it's removed 77,000 signatures and is investigating.
Work and Pensions Secretary Stephen Crabb says the Conservative Party needs a leader who can unite the UK.
Mr Crabb, who has been touted as a leadership contender, says that whoever takes over as prime minister must be someone who can talk to Scotland's First Minister Nicola Sturgeon.
Taoiseach Enda Kenny says the UK's decision to leave the EU should not have an impact on the Republic of Ireland's budget next year.
Mr Kenny says the flow of trade and services from the Republic to the UK should not be immediately impacted on, but adds that his government will take steps to protect economic stability.
Boris Johnson says the UK will continue to "intensify" co-operation with the EU after the country's vote to leave.
In his column in today's Daily Telegraph, the leading Leave campaigner said: "I cannot stress too much that Britain is part of Europe, and always will be."
Northern Ireland is "in an era of uncertainty" that will last years, UUP leader Mike Nesbitt says during the assembly debate on the UK's vote to leave the EU.
"Why is there no contingency plan to deal with this calamity?" he asks.
