The Tories' leader in Scotland has hailed an "incredible result" which looks likely to put the Conservatives in second place north of the border, ahead of Labour.
Ruth Davidson - who won the Edinburgh Central seat from the Scottish National Party (SNP) - said her campaign had focused on providing a "strong opposition" to the ruling SNP.
She also admitted she realised those who had voted for the party were unlikely to be "true blue Conservatives".
I fully recognise and understand there are many people that have given us their vote for the very first time, not because they're true blue Conservatives, but because there's a job of work they want us to do.
I hope the message that was resonating was of being a strong opposition, to hold the SNP to account, to saying no to a second independence referendum, to respect the decision that our country made and to really focus on the things we're paying a government to focus on, on schools, on hospitals, on public services.
That's what people want.
Labour's leader in Scotland has said she was "heartbroken" by overnight election results which look set to push the party into third place, behind the Tories.
Kezia Dugdale said it was clear even the Conservative candidates had not expected to perform as well as they had.
[I'm] heartbroken, without question. You can see from the reaction of the Tories that they are indeed surprised about how well they've done tonight.
There's no doubt that our defeat for the Labour Party is painful, but it is not the end of our campaign. We will continue to argue for Labour values, Labour ideas and Labour principles.
She also ruled out stepping down, saying "burning through leaders" was "not the answer".
