Ruth Davidson will join the House of Lords on Tuesday under the title Baroness Davidson of Lundin Links.
The title of the former Scottish Conservative leader comes from the village of Fife where she grew up and where her parents still live, the party said.
Ms Davidson, 42, who served as MSP from 2011 to 2021 and stepped down as chief in August 2019, is the fifth former Scottish chief to be appointed to the Lords.
She said her role would be to “ensure that all UK-wide laws are fit for purpose” and said her areas of particular focus include gambling reform, end choices of life and “the reform of the House of Lords into a democratic chamber”.
Ms Davidson said: âThis is important work and it is vital that it be undertaken by a mix of people from all walks of life and from all parts of the country.
âAs a teenage modern studies student learning politics at Buckhaven High School, I didn’t believe someone like me could have the chance to serve in not one, but two parliaments.
âI hope to build on all the experience I have gained over the past decade at Holyrood and put it to use in my new role.
Earlier this month, Ms Davidson said there was’ no chance ‘she would become Boris Johnson’s next Scottish secretary and that commitments to her family mean she won’t accept any’ big work âuntil her son is in school.
Ms Davidson became the first UK party leader to give birth in office when she welcomed baby Finn in October 2018 with partner Jen Wilson.
