Scottish Conservative MSP Alex Johnstone says there is a need for scenario planning.

The Finance Committee deputy convener says Mr Mackay agreed to share scenario planning when he came before the committee.   

Mr Johnstone says the levels of budget information is crucial. 

Finance Secretary Derek Mackay says the chancellor has abandoned the economic policies of his predecessor.

Mr Mackay says the Brexit vote will have a profound impact on the UK and Scottish economies.

He says there is an increased complexity in the budget process.

Scottish Labour leader Kezia Dugdale asks exactly what will be published between now and the the 15th December.

Mr Mackay says he will provide additional strategic information to assist committees, with the Autumn Statement and the draft budget, by the end of the October recess.

Scottish Conservative MSP Adam Tomkins says effective, robust parliamentary scrutiny is the lifeblood of our democracy.

Mr Tomkins says Mr Mackay has failed the test. 

He says it has been obvious that Mr Mackay is "pulling a fast one", or if that's not parliamentary language he says, "pulling the wool over the committee's eyes".

Labour MSP Alex Rowley says he hopes the minister will listen to pleas for a three year budget cycle.

Mr Rowley says Derek Mackay had previously pledged to provide  budget scenario information, so what has changed?

The Labour MSP says the situation is not satisfactory and the minister should not go back on his word.

Scottish Lib Dem leader Willie Rennie praises SNP MSP and Finance Committee convener Bruce Crawford, but accepts this may leave him "squirming in his seat".

Mr Rennie calls for more detail ahead of the draft budget being published.

He says the Fraser of Allander Institute has managed to make five year projections, so the government should be able to provide indicative figures for one year.

The Lib Dem MSP says the resistance from the minister may, he fears, be concerns about the SNP manifesto commitments.

Scottish Green Party co-convener Patrick Harvie praises Bruce Crawford and recognises the difficult position Derek Mackay is in.

Mr Harvie says the opposition parties could have insisted on a substantive debate with amendments and a motion to be voted on.

He says the opposition chose not to do that in an effort to ensure proper scrutiny of the draft budget.

The Green MSP says the committees need to consider the Scottish government's plans.

He says he hopes the cabinet secretary takes the opportunity to give more detail about information that will be made available.

Mr Mackay intervenes says he thinks there is room for agreement around this, to which Mr Harvie replies that is what we were discussing a month ago.

Scottish Labour MSP James Kelly says he finds the finance secretary's response "disappointing".

"What we got was seven minutes of absolute waffle", he says.

Mr Kelly says it is "disingenuous" of Mr Mackay to tell everyone how difficult it is to produce draft figures. 

"There is no excuse", he says.

The Labour MSP says Mr Mackay is determined to "curtail" and minimise the debate. 

He says Mr Harvie's motion gives Mr Mackay another chance to respond appropriately and if he doesn't he is treating parliament with contempt.

Conservative MSP Graeme Simpson says the Scottish government does not like scrutiny.

"Derek Mackay can bleat all he likes about the timing of the Autumn Statement but it is a pathetic excuse."

Mr Simpson says Derek Mackay is taking us to the bottom of the pile and that is simply not good enough.

SNP MSP Kate Forbes says Mr Hammond and Ms May are at the controls and, with Brexit, it is not a normal year so the Scottish parliament cannot expect a normal budget.

Ms Forbes says the UK chancellor is likely to slash the Scottish budget further.

She says it would be "downright irresponsible" to publish figures ahead of the Autumn Statement. 

Scottish Labour leader Kezia Dugdale says the SNP are attempting to deliver less scrutiny of the budget.

Ms Dugdale says the minister, by refusing to publish budget scenario planning and indicative figures, is treating this parliament with contempt and is going back on his promise.

Mr Fraser says the concern is the finance secretary has now gone back on his word to the committee and is providing less information.

The Tory MSP says budget scenario planning information and indicative figures.

He says it is very disappointing we are seeing budget scrutiny truncated.

Former Finance Secretary John Swinney intervenes and says the draft budget is delayed due to the delayed Autumn Statement.

Scottish Conservative MSP Murdo Fraser says he regrets the finance secretary has decided to "brazen it out", rather than listen to the parliament.

Mr Fraser says the majority of MSPs backed Patrick Harvie's motion calling for more scrutiny.

Scottish Green co-convenor Patrick Harvie has lodged a motion of his own, agreeing with the committee and "urging" the Scottish government to put its scenario planning information into the public domain.

This motion won support from every single opposition MSP, meaning a majority of members support Mr Crawford's committee - although it is not scheduled for debate.

Mr Harvie said that opposition members "could have forced a vote", but said that "for many it's about a better budget process, not engineering a government defeat for the sake of it".

Mr Mackay says he is willing to provide the committee with additional strategic information ahead of the publication of the draft budget.

The finance secretary says he cannot provide a draft spending plan and budget ahead of the 15th of December.

Scottish Green Party co-convener Patrick Harvie says a majority of MSPs have backed more information being given to the committee.

Mr Harvie says the committee has "bent over backwards" and calls for more from the finance secretary to allow the finance committee to do its job. 

Mr Mackay says he cannot produce a "credible" draft budget ahead of the Autumn Statement.
