SHE came, she saw, she squandered.

Johann Lamont had it on a plate yesterday.

Bank of England governor Mark Carney had teed things up exquisitely for her with a speech on how a currency union with sterling would force an independent Scotland to "cede sovereignty" to London, a phrase virtually hand-crafted for dinging off Alex Salmond's bonce.

All the Labour leader had to do was throw, and the FM was surely in for a pounding (geddit?)

All the damage was to Ms Lamont's feet, as she dropped clanger after clanger on them in a giddy self-destructive spiral Justin Beiber would have been proud of.

Mr Salmond's defence was to list the things Scotland would control outright, including taxes, employment law, the minimum wage, and the power to expel Trident and dodge a second Iraq.

Ms Lamont said his arrogance was verging on delusion: "This is a ludicrous defence by a man who used to cry freedom but who now gives us a list of wee things that we could do -"

At which the SNP backbenches - apologies for the parliamentary jargon - went absolutely tonto.

"Wee things?" MSPs mouthed in amazement. Labour thought those were wee things?! The FM seemed in a state of bliss.

Ms Lamont smiled thinly, like a condemned man hearing the firing squad joke, and waited for the shots to ring out; she didn't wait long.

"Does she really believe that the bedroom tax, the transformation of childcare, abolishing nuclear weapons in this country and not getting dragged into illegal wars are wee things?" asked Mr Salmond in disbelief.

"Is that the Labour Party's proposition to the people of Scotland? That these are wee things?"

A rapid U-turn was needed, but Ms Lamont instead simply kept digging, letting out a stream of nonsense as she buried the last of her credibility.

"Most of the things that the FM mentioned he could do right now..." she burbled.

"What the FM is proposing could give this Parliament less power than we have now."

The Nats rolled in the aisles like pennies.

Ms Lamont? She was tender all over.
