Nicola Sturgeon has said she still doesn't know where Theresa May is willing to compromise on Brexit after talks with the Prime Minister in Westminster.

The First Minister warned Scotland's interests are "in jeopardy" and also cautioned Labour leader Jeremy Corbyn to be "very wary of signing up" to a deal with May.

She was speaking in London after meetings with the PM and also with Corbyn earlier in the afternoon.

A Downing Street spokesman said the discussions had been about looking at the "next steps" for Brexit and added May urged Sturgeon to "come together" to deliver for Scotland and the UK.

It comes as MPs voted to reject a fresh round of "indicative votes" on Brexit options next week in remarkable Commons scenes.

Speaker John Bercow was forced to settle a tie of 310 each to the ayes and noes, following a precedent last used in 1993 which favours the status quo and voting no.

On Tuesday, the Prime Minister announced there needed to be a further extension of Article 50 in order to delay the Brexit process.

Speaking from Number 10, she offered to sit down with Corbyn to try to agree an EU withdrawal plan she can take to Brussels next week to delay exit beyond April 12.

The First Minister said Wednesday's meeting had been "an open conversation".

But she added: "It's still, to be frank, not entirely clear to me where the Prime Minister is prepared to compromise.

"She's keen to know where others might want to compromise but is not being particularly open about where her red lines might be removed and where she sees the room for compromise on her part is.

"I suppose overall my concern is that in the rush to reach some compromise with the clock ticking, what will happen over the next few days, if anything happens over the next few days, is that a bad compromise will be reached.

"People will probably breathe a sigh of relief that some agreement has been reached but then very quickly realise that it's not in the interests of the UK, it will satisfy no one, and of course, would be open to being unpicked by a Prime Minister that is not Theresa May, perhaps Boris Johnson."

Sturgeon also warned Corbyn: "I would be very wary about signing up to anything that may not be able to be delivered - in fact, may not be enough in the first place."

Asked by STV's Westminster correspondent Kathryn Samson if a deal with a customs union is the best compromise, the FM replied: "No, it's not.

"Customs union on its own doesn't, in my view, come close to protecting Scotland's interests.

"Freedom of movement is a big issue for Scotland that I appreciate is not always easy for politicians to address and perhaps is not the same issue in other parts of the UK.

"But the Scottish economy needs to have the ability to attract workers to come from across Europe."

Commenting on the meeting, a Downing Street spokesperson said: "The Prime Minister met with First Minister Nicola Sturgeon to discuss yesterday's Cabinet meetings and the next steps in delivering the UK's exit from the European Union in a smooth and orderly way.

"The Prime Minister made clear that this delay and division across the United Kingdom cannot continue and she is meeting with the leader of the opposition to find a proposal that can command the support of the House of Commons to allow the UK to leave the EU as soon as possible.

"She added that Brexit is a decisive moment in our history and we must come together to deliver for people in Scotland and the whole of the UK."

A Labour spokesman said of Corbyn's meeting with May: "We have had constructive exploratory discussions about how to break the Brexit deadlock.

"We have agreed a programme of work between our teams to explore the scope for agreement."

Meanwhile, Holyrood's presiding officer has confirmed the Scottish Parliament will meet during recess if the UK is due to leave the EU without a deal next Friday.

Ken Macintosh confirmed the Parliament would be recalled from 1pm next Thursday in that situation.

He described the matter as a "developing situation" and said MSPs may not get the suggested two days' notice.
