Tory MSP John Lamont says elected representatives from Scotland are currently debating the bill.

Mr Lamont says when the debate affects legislative powers devolved to Scotland the Scottish Parliament, will of course, have its say.

The Tory MSP says Prime Minister Theresa May has given the Scottish government "every opportunity to engage" in this process.

Tory MSP John Lamont says he is somewhat  surprised there is no LCM to vote on.

Mr Lamont says Mr Russell has said triggering Article 50 required the approval of Holyrood.

He says the Scottish government's default position is to try to manufacture a grievance out of nothing.

It is a matter for Scotland's other parliament to decide on, says the Tory MSP.

Here is the Scottish Conservative amendment.

The Brexit minister says the Scottish government does not know the date of submission of Article 50.

Mr Russell says the Scottish government will go on trying to get the UK government to engage with it right up until the last moment.

He says the Scottish Parliament has always worked with London, Cardiff and Belfast. 

This is met by laughter from the Tory benches.

Mr Russell says this government can do no other than recommending a vote against the triggering of Article 50.

Mr Russell says in December the Scottish government published Scotland's Place in Europe.

The Brexit minister says the paper made practical proposals.

He says the parliament agreed to keep Scotland in the single market.

The minister says the UK government has ignored these events. 

He says the UK government set out its proposals for Brexit without any consultation.  

Mr Russell says last week there was a threat to walk away dragging us on her coattails without any deal. 

He says: "The attitude of the UK government has to change."

Judges at the Supreme Court rejected the Scottish government's argument that Holyrood should get a say on the triggering of Article 50.

The court decided that MPs must have a say on starting the formal process of Brexit via an act of parliament.

However, they also rejected arguments from the Lord Advocate that devolved administrations should also have a say.

First Minister Nicola Sturgeon has pledged to hold a Holyrood vote on the matter regardless of the ruling.

She said there remained a "clear political obligation" on the UK government to consult devolved administrations, adding that "it is becoming clearer by the day that Scotland's voice is simply not being heard or listened to within the UK".

Mr Russell says he does not accept there is a majority for such a narrow vision of a Brexit.

Scottish Green MSP Patrick Harvie asks if it is clear that many leave campaigners were saying we would not be taken out of the single market.

The Brexit Minister agrees saying the leave campaign was disingenuous on many points. 

UK government Ministers wanted to invoke Article 50 of the Lisbon Treaty, the formal process for leaving the European Union, without consulting the Westminster parliament.

Campaigners disputed this, saying the referendum result alone does not give ministers the power to change the British constitution and supersede legislation.

The Supreme Court justices backed the challenge by eight votes to three, with President Lord Neuberger summarising their ruling as: "The Government cannot trigger Article 50 without an Act of Parliament authorising it to do so."

With Jeremy Corbyn pledging the support of Labour MPs to backing the government on Article 50, the defeat in court is not expected to derail the Brexit process, although it could pose complications.

The SNP have vowed to vote against invoking Article 50 if it does go to a vote at Westminster, while the Lib Dems have said they will oppose it unless there is a referendum on the final Brexit deal.

Mr Russell says he has taken part in meeting after meeting yet so far the UK government has offered nothing.

The Brexit minister says this is a debate is about the sort of country the UK wants to be.

He says a hard Brexit will lead to a hard Britain.

Mr Russell uses his motion to say all but one of Scotland’s MPs agrees that the UK government’s European Union (Notification of Withdrawal) Bill should not proceed.

The Brexit minister says the UK Government has set out no provision for effective consultation with the devolved administrations on reaching an agreed UK approach to the negotiations on implementing Article 50, external.

He says it has refused to give a guarantee on the position of EU nationals in the UK.

Brexit Minister Mike Russell says Scotland is being forced to leave the EU against its will. 

Mr Russell says the Scottish government opposes the hard Brexit that is being proposed.

He says this vote is symbolic.

The Brexit minister says the UK government has left unanswered a range of detailed questions covering many policy areas regarding the full implications of withdrawal from the single market, and has provided no assurance that a future parliamentary vote on the outcome of the negotiations will be anything other than irrelevant.

That is because as withdrawal from the EU follows two years after the invoking of Article 50 , externalif agreement is not reached in the forthcoming negotiations, unless they are prolonged by unanimity, he says.

Brexit Minister Mike Russell leads a debate on Article 50. 

The Scottish Parliament is expected to formally oppose the UK government starting the Brexit process when MSPs vote on the issue later.

The Supreme Court ruled last month that there was no legal need for Holyrood to give its consent to the triggering of Article 50.

But First Minister Nicola Sturgeon said she would let MSPs have a say in what will be a largely symbolic vote.

The SNP tried to block the UK government's Brexit bill last week.

Only one of Scotland's 59 MPs - Scottish Secretary David Mundell - supported the bill, but it ultimately passed its first parliamentary hurdle by 498 votes to 114.

Here is the Scottish government motion.

Labour MSP Neil Findlay moves a motion without notice to extend the debate by 30 minutes so that more MSPs can join the debate even if not selected by the party whips.

Mr Findlay says "in the interest of democracy" the debate should be extended.

Presiding Officer Ken Macintosh says he will not consider the motion at this time.

Mr Findlay says he would like it to be put to a vote as he has moved the motion.

Mr Macintosh says he will not consider it at this time.
