Scotland will have no veto over Brexit, the UK Government's chief legal adviser has said.

Attorney general Jeremy Wright explicitly ruled out a veto for any of the devolved administrations over the process of Brexit but said they should all be consulted on and involved in the negotiations with Europe.

He said Brexit "means all of the United Kingdom", in answer to a question from a Conservative MP who worried the UK could be "held to ransom by the Scottish Nationalists".

The attorney general added Article 50 of the Lisbon Treaty, which must be invoked to formally begin Britain's withdrawal from the EU, would only be triggered "when we're ready".

Alison Thewliss, SNP MP for Glasgow Central, asked about the Scottish position on Brexit given the country's backing for Remain in the EU referendum, when 62% of voters opted to stay in.

Thewliss said: "The Prime Minister has indicated that she'll not trigger Article 50 in the UK until there is a UK approach to Brexit.

"Do you agree that a legislative consent motion is required before the government has legal authority to trigger Article 50?"

Wright said all of the UK's devolved administrations should take part in the Brexit process.

He added: "That does not mean that any of the parts of the United Kingdom have a veto over this process, and so consultation most certainly, but veto I'm afraid not."

Tory MP David Nuttall, who represents Bury North, was critical of the SNP, telling Wright: "I'm quite happy with the government consulting with the devolved administrations.

"But what concerns me is that we don't finish up being held to ransom by the Scottish nationalists.

"The point is that whatever the government try and do they will never be able to satisfy the Scottish Nationalists."

Nuttall asked: "Can you please reassure me and my constituents who voted overwhelmingly to leave the European Union that their wishes will not be frustrated by the Scottish National Party?"

Wright reiterated Prime Minister Theresa May's view on respecting the Brexit result, adding: "That means all of the United Kingdom."

He also faced a series of questions about the timing of Article 50, after Brexit secretary David Davis suggested it could be invoked before the end of this year or at the start of the next.

Theresa May has insisted it will not happen before the end of this year.

SNP MP for Glenrothes Peter Grant asked the attorney general whether May or Davis was correct on the UK's official position on triggering Article 50.

Wright responded: "I don't think there is any confusion. What we must do is make sure there is clarity about the United Kingdom's position going into these negotiations, that we've done that work before we begin them.

"It is for the United Kingdom to determine at which point Article 50 is triggered. We should do so when we're ready."
