One of the leading backers of a Scottish Parliament has claimed that successive governments have failed to reform schools and hospitals.
Nigel Smith, a businessman who chaired the cross-party campaign in favour of devolution in 1997, also blamed MSPs for failing to hold Ministers to account.
Smith led the official Yes campaign, Scotland Forward, which helped deliver a referendum victory for a devolved Parliament with tax-varying powers.
However, although supporters claimed devolution would improve public services, many outcomes have got worse rather than better.
On the SNP Government’s watch, the attainment gap remains wide and targets for NHS waiting times will not be met until 2021.
Smith, responding to suggestions that no more powers should be devolved to Holyrood, wrote: "The Scottish Parliament has not been a failure for it has legislated imaginatively, in many areas, but in the biggest areas such as education and health...it has badly disappointed.”
On education , he continued: “I blame all Scottish governments, including the current one, for the main part of this failure.
"But I would also include the parliamentarians who have failed to hold their government to account, allowing poor policy to persist."
He also claimed more devolution would lead to calls for more MSPs, a “revised” electoral system, and a new front for “constitutional navel-gazing while another generation of Scottish children languish”.
