Russell Findlay's first question is about gangland violence in the aftermath of two Scots with gang connections being shot dead in Spain.

Findlay says rival gangs have "waged war" on Scotland's streets since the dawn of devolution - calling them "parasites" who grow rich by preying on the most vulnerable.

The Tory leader - who was subjected to an acid attack in 2015 - mentions how gangs go after journalists and police. He asks whether John Swinney has failed to tackle organised crime.

Swinney says he agrees with a lot of what Findlay says - that organised crime is intolerable and unacceptable, and requires the "forensic attention" of police to tackle it.

However, he says this is already being undertaken "on a relentless basis" by police and the criminal justice authorities, and that he doesn't agree with Findlay's conclusion.

First Minister John Swinney has now taken his position on the front benches and is about to take questions.

First up is Scottish Conservative leader Russell Findlay, who we believe will ask about knife crime.

The attention of MSPs may be elsewhere today, given the by-election taking place in Hamilton, Larkhall and Stonehouse.

The parliament is only sitting for about an hour, to cover general and first minister’s questions, with no committees meeting. More time for members to go knock on doors.

Leaders may be tempted to tout for votes in the chamber too – frankly they’ve been doing little else for the last six months.

If they do, you won’t hear much from us about it; there is to be no reporting of any campaigning while polls are open.

But there are still plenty of substantial topics to be put to the first minister, where business can go on as usual.

Ever wonder why you see so many pictures of dogs outside polling stations during election coverage?

In part, it's because broadcasters like the BBC are not allowed to report details of campaigning or election issues while polls are open.

We also can't publish the results of any opinion polls on polling, nor give indication to how people may have voted before polls close - the latter is a criminal offence.

These rules come under the Communications Act 2003.

Good morning and welcome to our live reporting on First Minister's Questions.

We'll be providing lighter coverage of what's said in the chamber this week as the polls are open in the Hamilton, Larkhall and Stonehouse by-election.You can watch the action by pressing play at the top of the page.
