East Renfrewshire MP Kirsten Oswald has been elected unopposed as the new SNP Westminster Deputy Leader.
Mrs Oswald, who won the seat from the Conservatives in the 2019 general election, will join Ian Blackford in leading the SNPs in Westminster.
Kirsty Blackman stepped down from the post last week, citing the impact of lockdown on her mental health.
Mrs Oswald said she was delighted to have been elected.
She added: “As we continue to tackle coronavirus, SNP MPs will press the UK Government to deliver the financial powers and support that people, public services and businesses in Scotland need to manage this unprecedented emergency and secure a strong recovery.
“This crisis has exposed the deep inequality caused by decades of Westminster cuts. There can be no return to business as normal. As Scotland seeks to build a fairer society and escape the growing threat of a Tory Brexit, the case for independence has never been stronger.”
SNP Westminster Leader Ian Blackford said he was looking forward to working with her in Westminster, to provide a strong voice for Scotland.
Mr Blackford added: “This is an important time as we deal with the Covid-19 crisis and look to build a fairer Scotland.
“With the threat of a Tory Brexit growing, and crucial decisions over the economic emergency, Kirsten will play a key role as we hold the Tory Government to account.”
