The constituency of Gordon was a closely-watched battle in 2015 and it is set to fall under the spotlight again as the former First Minister fights for re-election.
Alex Salmond convincingly won the seat in 2015 as the SNP swept to victory across the country securing 27,717 votes and beating the Liberal Democrats into second place.
Under Sir Malcolm Bruce, the Lib Dems held the seat for more than three decades and won seven general election campaigns. And the Tories came a distant third place in 2015 with 6,807 votes and has to make significant gains in its vote share if it is to stand any chance of taking the seat.
But Scottish Conservatives leader Ruth Davidson has the constituency firmly within her sights and hopes a strong showing in last month’s council elections will see their support increase on Thursday. The party won the most first preference votes in all of the council wards across Aberdeenshire.
