Dumfriesshire, Clydesdale & Tweeddale

There will be considerable interest in whether Scottish Secretary David Mundell is re-elected.

Mundell regained the seat in 2015 with a majority of just 798 votes over the SNP's Emma Harper, elected to the Scottish Parliament last year.

Labour was third behind Mundell, with Ukip fourth and the Lib Dems fifth while the Scottish Greens came sixth with 839 votes.

The SNP's Mairi McAllan is fighting hard to get the seat and could be favoured by the Greens not standing. However, Mundell could also benefit form the decision by Ukip not to stand.

Edinburgh South

Will Ian Murray hold Edinburgh South for Labour?

Murray became the "last man standing" of Scottish Labour when the party lost 40 of its 41 seats in the May 2015 General Election.

A critic of Jeremy Corbyn, he stood down as shadow Scottish Secretary during the parliamentary coup against the UK leader which followed the EU referendum.

Murray held onto his seat in 2015, beating the SNP's Neil Hay by 2637 votes with the Conservatives coming in third.

This time he is up against the former SNP MSP Jim Eadie, while Stephanie Smith is the Tory candidate.

Perth and North Perthshire

The SNP's Pete Wishart has been the MP since the seat was created in 2005, and has a comfortable majority of 9,641 votes. However there was a big swing to the Tories in last year's Scottish Parliament election vote in 2016, with Deputy First Minister John Swinney, seeing his majority cut to 3,336. Perth and Kinross also voted by 60 per cent against independence.

The Tories had a strong showing in the local elections in Perth and Kinross, becoming the largest party on the council with a big swing in the vote. Ian Duncan, currently the Tories only Scottish MEP, is the party's candidate.

Dunbartonshire East

The SNP's John Nicolson has one of the party's smaller majorities - winning with 2,167 votes in 2015.

The constituency was a safe Lib Dem seat until the former BBC journalist won two years ago. He claimed 22,093 votes - enough to push sitting MP and former minister Jo Swinson, with 19,926, into second. Swinson is standing again. The Lib Dems have concentrated substantial resources in the seat with both Scottish leader Willie Rennie and UK leader Tim Farron making campaign visits. Nicolson and the SNP are fighting hard to keep it and Sturgeon has visited the seat during the campaign on a number of occasions.

Renfrewshire East

Another constituency observers will be keenly watching will be Renfrewshire East.

In one of the many surprises of the 2015 General Election, the SNP's Kirsten Oswald beat the then Scottish Labour leader Jim Murphy by 23,013 to 19,295 votes. The Tories came third with 12,465 seats.

Jackson Carlaw took the roughly parallel Holyrood seat of Eastwood for the Tories at last year's Scottish Parliament elections, and the Tories will be campaigning hard to win it in June. Their candidate is Paul Masterson.

Labour's has put up former Better Together campaign director Blair McDougall. McDougall has received considerable backing from former Labour Prime Minister Gordon Brown and ex Chancellor Alistair Darling. Corbyn has given him less of a mention.

But the presence of two staunch pro-Union candidates in the contest could benefit Oswald.

Edinburgh West

This is a fiercely contested SNP-Lib Dem battleground. The seat was gained by the SNP in 2015 - but the winner, Michelle Thomson, ultimately ended up sitting as an independent after a police investigation and was subsequently denied the SNP ticket for 2017. She decided against contesting the seat as an independent.

The SNP candidate is Toni Giugliano, who contested the corresponding Holyrood seat in 2016, losing to Alex Cole-Hamilton - who is now heading up the whole Scottish Lib Dem election campaign.

The candidate tasked with re-taking the seat for the Lib Dems is Christine Jardine, a former coalition government advisor who stood in Aberdeenshire in the 2015 and 2016 elections.

Berwickshire, Roxburgh and Selkirk

This is Scotland's most marginal seat and was gained by the SNP in 2015 by just 328 votes, ousting former Scottish Secretary Michael Moore.

The Tories are determined to gain the seat this time round, with sitting local MSP John Lamont hoping to take it at his fourth attempt.

He held the corresponding Holyrood seat by a comfortable margin in 2016, but has now resigned that seat in a bid to finally win a place at Westminster. Labour, meanwhile, have put up Ian Davidson, who was an MP in Glasgow for 23 years.

Aberdeen South

Former Aberdeen City Council leader Callum McCaig took the seat from long-time Labour incumbent Dame Anne Begg in 2015, courtesy of a 19.8 per cent swing. Tory candidate is MSP Ross Thomson, another former city councillor who came third in the 2015 contest before entering Holyrood via the North East list in 2016.

The Tories are banking on pro-Brexit sentiment playing a big role in this election, and Thomson was one of the more prominent Leave campaigners north of the Border.

Moray

Could the SNP's depute leader Angus Robertson be ousted by the Tories?

All of Scotland's local authority's areas voted Remain in last year's EU referendum, but Moray had the smallest Remain majority with just 50.1 per cent. Boosted by local Eurosceptism, the Tories fancying their chances.

Robertson is one of the SNP's giants, a high profile national figure who commands considerable support and respect.

Tory candidate, meanwhile, Douglas Ross, elected a MSP last year, has been plagued with criticisms over his activities as a football referee.

Ross, who is the Tory's justice spokesman, faced calls for his resignation from membership of Holyrood's justice committee after missing one of its meetings while on refereeing duties in Portugal last November.

The SNP called on Ross to quit from the Justice Committee or give up his refereeing job. It was not the first time Ross’s footballing commitments interfered with his political ones. Two months earlier Ross missed committee meetings, a parliamentary vote and local meetings about MoD base closures while he attended a five day refereeing course in Switzerland.

Glasgow North

Could Patrick Harvie take Glasgow North for the Scottish Greens?

The SNP's Patrick Grady, a former national secretary of the party, took the seat in 2015 with a 9,295 majority with the Greens coming fourth.

However, the Greens improved their performance to come second in the parallel seat of Glasgow Kelvin at last year's Holyrood elections.

Harvie, who was the Greens' candidate, missed out to the SNP's Sandra White in the first past the post constituency contest, but gained a seat through the regional ballot.
