THE Prime Minister was bang on when he described devolution as Tony Blair’s “biggest mistake’ and a “disaster”.

Cue a chorus of condemnation, all from those vested interests who have grown powerful on the slow fragmentation of the United Kingdom.

For Mr Blair it was simple; give the separate nations enough powers to mollify their demands for self-rule and boost Labour’s support in the process.

Well, he failed in both.

His Party’s MPs were wiped out by a resurgent SNP, who took seat after seat on a wave of nationalism that now threatens the break-up of our Union.

It’s ironic that this ruinous policy is, in the main, funded by us.

A bloated and vastly expensive Scottish parliament has 129 members representing just four million Scots.

And, under the notorious Barnett formula, Scots receive approximately £2,000 more per head annually than the English.

Even with this transfer of power and wealth, Scotland’s record on education, employment and health care is appalling.

Irresponsible policies, like closing the nuclear submarine base at Faslane, along with 9,000 jobs, only highlight the SNP’s inability to govern.

Instead, they focus on fomenting long-held grievances against England, which we see all too clearly in the Commons.

Having failed to gain independence in 2014, and the SNP’s promise that it was a once in a generation vote, Nicola Sturgeon wants another next year.

The situation, along with an incompetent Welsh administration and problems at Stormont, confirms that any further home rule must be considered carefully.

Certainly, it raises doubt about increased regional government.

Should the Scottish independence question be asked again, I believe strongly that the entire United Kingdom should vote.

After 300 years of joint endeavour, it concerns us all.

As I’ve always said, united we stand, divided we fall.
