UK government orders review of post-Brexit farm funding
The UK government is to set up an independent review into how farm funding should be distributed around the United Kingdom after Brexit.
An independent advisory panel will look at subsidies going to England, Scotland, Wales and Northern Ireland to ensure they are "fairly split".
NFU Scotland has said it was "bitterly disappointing" that it would not address previous funding decisions.
The Scottish government said farmers should receive the £160m they are due.
According to the UK government, the Barnett formula alone will not be used as a basis for distributing funds to farmers after 2022.
The review is to recommend how cash will be shared out after the UK has left the EU's Common Agricultural Policy (CAP).
The recommendations will be "informed" by previous allocations of convergence funding but "will not revisit these decisions or redistribute money that has already been committed", the Department of Environment, Food and Rural Affairs (Defra) said in a statement.
Scottish farming organisations and the Scottish government have argued that Scotland is owed about £160m of EU convergence uplift payments to the UK for the period 2014-2020.
Environment Secretary Michael Gove said the review would consider each country's circumstances, including environmental, agricultural and socio-economic factors, including farm numbers and sizes.
The review will be led by Lord Bew, the former chairman of the Committee on Standards in Public Life.
The panel will include representatives from each of the devolved administrations.
Mr Gove said: "This important review, led by Lord Bew, will explore how we can deliver funding for farmers that supports the individual needs of England, Scotland, Wales and Northern Ireland.
"We are committed to making sure that future funding is fairly allocated, and are also confirming that the government won't simply apply the Barnett formula to Defra's funding beyond this parliament.
"Meanwhile our funding commitment up until the end of the Parliament gives more certainty for UK farmers than any other EU member state."
A spokesman for NFU Scotland said: "Today's announcement is long overdue.
"Whilst it is an important step forward in recognising that there is an equitable intra-UK allocation of domestic farm support funding to the end of this parliament, it is bitterly disappointing that the review will not redress the funding which Scottish farmers and crofters have lost out on since this decision was implemented in 2014."
He added: "This review must be about agreeing the baseline for future funding allocations beyond the current parliament and existing UK Government commitments to 2022.
"This baseline is an essential cornerstone on which Scotland will build its future agricultural policy."
A Scottish government spokesman said: "We are disappointed that the terms of the review have been announced before the Scottish government has received a response to our concerns.
"This review must not simply be an exercise in playing for time in delivering funding to Scotland's farmers which is rightfully theirs.
"The only reason the UK, as the member state, qualified for an uplift is because of Scotland - therefore, the only fair funding solution for Scottish farmers and crofters is for them to receive the £160m in convergence funding due to them. Anything less than this is completely unacceptable."
