LEADING Scottish politicians are set to do battle in the latest pre-election debate.

In a special show ahead of the Holyrood ballot, BBC Question Time will give a platform to the country’s five main parties as they take questions from the public.

Nicola Sturgeon will not be on the show, opting instead to do radio phone-ins.

The SNP will instead be represented by depute leader Keith Brown.

The former economy secretary, and veteran of the Falklands, co-ordinates his party’s independence campaigning.

Also on the panel is Scottish Tory leader Douglas Ross, who has recently been under fire for refusing to accept Scotland has a democratic route to independence. The Moray MP is seeking to win a dual mandate for Holyrood and Westminster.

Representing the Greens is co-leader Lorna Slater, who impressed during the BBC leaders’ debate earlier this month. The renewable energy engineer will be hoping to put forward the green case for independence.

And finally there’s LibDem chief Willie Rennie, who has led the party for a decade.

The programme, hosted in Edinburgh, starts at 10.45pm and will be presented by Fiona Bruce.

It will be aired on BBC One Scotland and iPlayer.
