On Gulhane on Politics this week, we focus on:

Spite - and the SNP in civil war;

Bite - Scotland's NHS is in crisis;

and Tight - Scotland's ever expanding waistline and the country's obesity crisis.

They say a week is a long time in politics – far less 2 or even 3. Since our last series, Nicola Sturgeon has resigned as SNP Party leader. A three-horse race campaign is underway for SNP members to elect a new leader - and the SNP faithful are now reduced to tearing lumps out of each other.

Leadership candidate Kate Forbes, the Finance Minister, equates Health Minister Humza Yousaf as mediocre – adding she would roll back some of Nicola Sturgeon’s flagship policies.

Humza, the SNP hierarchy’s preferred candidate, or Mr Continuity, shows contempt for Kate and her faith as she is a member of the socially conservative Free Church of Scotland.

That leaves candidate number three, Ash Regan, who says the SNP has lost its way – not exactly a robust endorsement of Nicola Sturgeon.

At First Minister’s Questions in the Scottish Parliament, the Scottish Conservative’s leader Douglas Ross was quick to rub it in.

Aside from this and knowing who will next lead the SNP and become First Minister, there is another question on everyone’s mind: Why did Nicola Sturgeon resign so suddenly ? I reflected on this at a recent conference of the Scottish Conservatives West of Scotland Region.

On March 27th the SNP membership will decide on its new leader and Scotland’s next First Minister.

For now, we can just sit back and watch the SNP in civil war and prepare to continue taking them to task – whoever ends up in our sights at First Ministers Questions – or, in my case, has the Health Secretary’s job when all the dust settles.

The British Dental Association says NHS dentistry in Scotland is in crisis. And this is on the SNP Government’s watch. Yet the Health Secretary Humza Yousaf – he who wants to be First Minister – well, Humza thinks he’s doing a great job !

So what’s the real picture ?

I caught up with Charlotte Waite, Director of the BDA Scotland to find out more about dentistry on the front line.

From mouths to waistlines: modern life, modern diet, and, for many, inactivity - this can result in obesity.

And in Scotland, the rate of obesity is seriously impacting the country’s health.

So what can we do about this ?

To look for answers, I met up with Lorraine Tulloch of Obesity Action Scotland - and we started by weighing-up, the true scale of the problem.
