Newly-elected SNP MP Brendan O’Hara said he was “deeply humbled” after a runaway victory in the Argyll and Bute constituency.
The award-winning television producer swept into Westminster on the tidal wave of SNP support across the county.
He polled 22,959 to oust Liberal Democrat Alan Reid, who finished in second place with 14,486.
Mr O’Hara said “Scotland has raised its voice” and promised “to work as hard as I possibly can. I will not let you down”.
The seat had been held by the Lib Dems since 1987, when it was won by the late Baroness Michie of Gallanach.
Ray Michie held the constituency until 2001 before standing down and Mr Reid had held the seat for the party since the 2001 election.
Mr Reid said it had been an honour to represent Argyll and Bute for 14 years.
He added: “I have made many friends here.
“I will continue to live here and work for the good of Argyll and Bute.”
In the independence referendum, Argyll and Bute voted No by 37,143 to 26,324; with a turnout of 88.2%.
At 28-years-old, the Conservative candidate Alastair Redman said there were plenty more opportunities for him to win the seat.
“Record numbers of non-traditional Conservatives are joining the ranks,” he said.
Caroline Santos was the first Ukip candidate to fight Argyll and Bute and she promised she would be back.
“I’m looking forward to the next one – this has paved the way and we are a party which is seeing its share of the vote increase,” she added.
Labour’s Mary Galbraith said there had been lots of positive feedback on the doorsteps.
She said: “On a personal level it has been really positive and we have had a lot of good policies.
“Obviously we were not going to withstand the tsunami that is flooding over Scotland right now.”
