Ross began his political career when he took up a post as a parliamentary researcher at the Scottish Parliament.
He was first elected to The Moray Council in 2007, representing the Fochabers-Lhanbryde ward, and became part of the Independent/Conservative administration.
He resigned from the council administration in December 2009 but continued as a councillor.
In 2012, he was re-elected to The Moray Council and again became part of the ruling administration group but was "ousted" from this in 2014, following a debate about school closures.

Ross stood as the Conservative candidate for Moray at the 2010 and 2015 general elections, coming second to Angus Robertson but increased his share of the vote by 5.0% in 2015.
He also stood as the Conservative candidate for the Moray Scottish Parliament constituency at the 2011 Scottish Parliament election but finished second to Richard Lochhead.
At the 2016 Scottish Parliament election, Ross increased his vote by 18.0% but again finished behind Lockhead.
However, he was elected to the Scottish Parliament after being placed first on the Highlands and Islands regional list.
He supported the UK remaining within the European Union in the 2016 membership referendum.

Ross stood again for the seat of Moray at the 2017 general election, challenging SNP deputy leader Angus Robertson.
He was successful in overturning Robertson's 9,065 majority with 22,637 votes, 47.6% of the votes cast, gaining a 16.5% swing to the Conservatives.
Having gained a seat at Westminster, Ross resigned from his seat in the Scottish Parliament.

In 2017, Ross said during an interview that if he was Prime Minister for a day "without any repercussions", he would "like to see tougher enforcement against Gypsy Travellers".
His remark was criticised, including by Naomi McAuliffe of Amnesty International.
Ross apologised for his use of language.
The Scottish Football Association launched a disciplinary investigation into his remarks, which did not lead to any formal disciplinary action, but warned him to pay attention to his use of language.

SNP and Labour spokespeople criticised Ross for missing a debate on Universal Credit in October 2017, due to his commitments as a football referee.
Shortly afterwards, Ross decided he would no longer accept referee appointments while the UK Parliament is sitting.

Despite backing remaining in the EU prior to the referendum, Ross stated Parliament should complete Brexit to "deliver the will of the British people".
He voted against Theresa May's Brexit withdrawal agreement at the first round of voting and was absent for the second following his wife going into labour.
He supported Mark Harper then subsequently Boris Johnson in the 2019 Conservative Party leadership election.

Ross was re-elected at the 2019 general election with a reduced majority.
He was then appointed Parliamentary Under-Secretary of State for Scotland, replacing Colin Clark who had lost his seat in the election.
He resigned from this role on 26 May 2020, in protest against Dominic Cummings continuing to serve as Chief Adviser to the Prime Minister after having travelled over 260 miles (420 kilometres) from London to Durham during the COVID-19 lockdown period.

Ross announced his candidature in the August 2020 Scottish Conservative Party leadership election after Jackson Carlaw's resignation on 30 July 2020.
On 5 August, he won the contest unopposed and became leader.
On 11 August, he conducted a reshuffle where he made Ruth Davidson the Leader of the Conservative Party in the Scottish Parliament, dismissed Annie Wells and Liam Kerr from their deputy leadership positions and did not give Carlaw a position.
He also announced plans to run for a seat in the 2021 Scottish Parliament election and succeed Davidson as his party's leader in Holyrood.
