Mr Russell says there has not been agreement on how the devolved governments will be involved in the second stage of negotiations.

Agriculture, environment and fisheries will be at the heart of these negotiations, all of which are devolved areas, he says.

The section of the document on justice issues is "unacceptable in tone and sentiment" the cabinet secretary adds, highlighting Scotland has a separate legal system to the rest of the UK.

The minister says if the basic free trade sought by the UK government is agree, Scotland's GDP would be 6.1% - or £9bn - lower by 2030 than if the UK remained a full EU member.

Mike Russell explains this statement is about the publication of the UK government's approach to negotiations with the EU.

The Brexit Secretary says the approach of this document will make people worse off financially in Scotland.

"The UK government is now in the hands of ideological extremists," Mr Russell tells the chamber.

He bemoans the lack of involvement of the devolved nations in creating this document.

Mr Russell, now officially known now as the constitution, Europe and external affairs secretary, says the devolved nations are once again being managed, not engaged.

So this is it. After three messy years negotiating the UK's exit from the EU, Monday was the day that trade talks finally began between the two sides.

David Frost, the UK's chief negotiator, arrived in Brussels in the afternoon, armed with 100 advisers and civil servants, preparing to spread themselves across 10 working groups, focusing on everything from fishing to financial services to truck drivers' cross-border access.

Negotiations are to take place once every two or three weeks from now until the summer at least, alternating between Brussels and London - with the prime minister insisting a deal must be struck by the year's end.

Brexit Secretary Mike Russell will now deliver a statement on the UK government negotiation mandate.

Social Security Secretary Shirley-Anne Somerville says the Scottish government expects everyone to be treated with consideration, dignity and respect when using NHS services.

The government supports the appropriate use of single sex exemptions by service providers where it is proportionate, adds Ms Somerville.

Ms McAlpine says NHS Greater Glasgow and Clyde's gender reassignment policy says a female patient distressed at the presence of a "male bodied trans identified person in the next bed", should be told that person is female.

Ms McAlpine calls on the minister to speak to the board about reviewing its policy.

The minister says women's rights must be protected by health boards, while abiding by the exceptions in the Equalities Act.

The Scottish government is proposing to make it easier to legally change gender. Supporters say the plans are vital to ensure transgender people are treated with dignity - but one woman who used hormones and surgery to become a man, only to regret the decision, has described the proposed reforms as "dangerous".

Sinead Watson says she didn't have any issues with her gender as a child.

It wasn't until she began to grow into a woman in her teens that a feeling of insecurity took hold, and she began to dislike her body and feel uncomfortable in her own skin.

When she was in her early 20s, she told BBC Scotland's The Nine, she typed into Google "something along the lines of 'I'm a woman, I wish I was a man'."

The results page introduced Ms Watson to the concept of gender dysphoria, defined by the NHS, external as discomfort or distress caused by a mismatch between biological sex and gender identity.

SNP MSP Joan McAlpine asks the Scottish government, in light of its commitment to uphold the single sex exemptions under the Equality Act 2010, what its response is to concerns that this could be undermined by allowing male hospital patients who identify as female, including those who have made no physical changes, to be placed in wards that match their gender identity.

MSPs quiz social security and older people ministers during portfolio questions.

Local Government Secretary Aileen Campbell says an additional £95m has been allocated to local government on top of that announced in the draft budget.

Mr Stewart says the recent £95m does not account for inflation and years of cuts and does not resolve the "blackhole" in capital funding.

Ms Campbell recognises challenges across the whole of public finance driven by ten years of austerity from the UK government.

Tory MSP Alexander Stewart asks what action the Scottish government will take to protect local authority services, in light of the claim by COSLA that the proposals in its draft Budget "will hit vulnerable communities the hardest".

The finance secretary explains her amendments are to give effect to the budget deal agreement with the Greens and also reflect revised portfolios.

All amendments are agreed unanimously by the committee.

MSPs are debating and voting on Stage Two amendments to the Budget (Scotland) (No.4) Bill, external.

A deal between the Greens and the SNP was struck last week, requiring changes to the bill.

Mr Cameron says it is "hypocritical" to complain about uncertainty around consequentials when the government has used those consequentials to reach a deal.

Ms Forbes replies: "If the UK government, if the Conservatives, fail to deliver on their promises that they made to the electorate in the December election and therefore we see a cut, whose fault is that?"

"I'm not here to give evidence, cabinet secretary, you are," says Mr Cameron.

And with that we move on to debate and vote on the budget amendments.

Tory MSP Donald Cameron asks if the cabinet secretary accepts the draft budget used Barnett consequential of £468m in excess of the Treasury's forecast of over £1.1bn as per the spending round of last September.

The finance secretary accepts that £1.1bn of additional resource budget was allocated at the UK spending round, to which she added £142m of anticipated consequentials from the forthcoming UK budget.

Ms Frorbes says that is part of the £468m with the remainder being capital.

The cabinet secretary tells the committee that the government has based decisions on the best available evidence.

The question will be if the UK government meets its commitments made during the election campaign, as the Treasury has continually cited the pledges in the manifesto, she adds.

The budget deal means an overall an increase of £60 for police spending:

• £18m to police services
• £13m for frontline services
• £5m for capital investments

SNP MSP George Adam turns discussion to police budgets and Ms Forbes says the government will have exceeded its commitment to maintain revenue budgets next year.

Labour MSP Alex Rowley asks about the fire service budget and whether enough cash has been allocated to meet the pay offer.

The finance secretary confirms the fire service budget is protected, but the Scottish government is not involved in pay negotiations with staff.

There is an uplift of £6.1m to meet modernisation aims for the fire service, she adds.

Mr Fraser says income tax reconciliations in the current budget came to £204m and the current projected sum for the following year is £550m.

How prudent is it to start spending future years' income, he asks, with a bigger issue to address in a year's time.

"This is a judgement call," replies the finance secretary, arguing she has protected the reserve and she has left £93m of resource borrowing headroom to address volatility and uncertainty coming down the line.

Kate Forbes points out there are issues with the fiscal framework which means her borrowing powers will not cover the income tax reconciliations at over £500m next year.
