The Welsh Government has responded to the news that its share of public spending per head is going up compared to equivalent Whitehall departments. It's issued a graph that shows what's happened over the years since devolution.
As public spending took off in the early years of devolution, the so-called 'Barnett squeeze' meant that Wales slipped from being 25% ahead of England to being 15% ahead. In other words, Wales got a smaller share of a cake that was getting larger.
It had fallen further by 2009 but has gone up again as the system is now limiting Wales' share of cuts, not increases. The fact that Wales gets higher spending per head is usually justified by our relative poverty and greater health needs but those factors aren't actually taken into account.
Figures released by the Treasury show that the process that has given the Welsh Government slightly smaller increases in funds than equivalent Whitehall departments has stopped. In fact it has gone into reverse, putting Wales more than 15% above England in terms of spending per head.
2011/12 15.0% more than in England
2012/13 14.6% more than in England
2013/14 15.1% more than in England
2014/15 15.5% more than in England
2015/16 15.8% more than in England
The Barnett Formula, invented to slowly bring Welsh public spending in line with England's, worked on the assumption that overall expenditure would keep going up. Now instead of restricting the Welsh share of any increase, it will limit the share of cuts.
The figures have been released under an agreement between the Welsh Government and the Treasury to monitor the figures for any return of the 'Barnett squeeze' on Welsh spending.
