The process of how the Scottish Parliament passes and scrutinises the Scottish Government's budget is to face a fundamental review.

A review has been called for following the passing of the Scotland Act 2016 which transferred more fiscal powers to the Scottish Parliament such as income tax.

Holyrood has also gained wider responsibility in recent years to now include around 15% of all welfare spending in Scotland.

The current budget process was created 17 years ago when the parliament was created.

The review panel will consist of officials from the Scottish Parliament, the Scottish Government as well as external public finance experts and academics.

Holyrood's finance committee chair Bruce Crawford said: "Holyrood's budget process was designed nearly 20 years ago, at a time when the Scottish Government's budget was largely determined by Westminster through the Barnett formula.

"With Scotland's new tax powers, the Scottish Government is about to become responsible for raising much more of what it spends, and will rely on tax forecasting in order to set out its draft budget before Parliament each year.

Crawford continued: "Understandably the government will want to rely on the most accurate forecasts of tax revenue possible in order to ensure confidence and credibility in its budget.

"Equally, however, the finance committee will want to ensure that any new budget process still includes sufficient time for proper parliamentary scrutiny."

The panel will consider the impact of the following on future budgeting:

Finance secretary Derek Mackay said he supports the aims of the review.

Mackay said: "I am very supportive of the establishment of the review group which will bring together representatives from the Scottish Parliament, Scottish Government and a panel of external experts to ensure there is meaningful scrutiny of the budget and an opportunity for Parliamentary engagement in the process.

"Scotland's budget process needs to evolve to take account of the complexities and opportunities associated with the Scottish Parliament's new powers.

"It is important to ensure that we develop a process that balances the time required for proportionate and effective Parliamentary scrutiny with the need to ensure that the information being scrutinised is as accurate as possible and based on the most up to date forecast information."

Mackay became finance secretary in the First Minister's cabinet reshuffle following May's Holyrood election.

The review will provide a report of is findings to the finance committee and ministers before the summer recess in 2017.
