Argyll and Bute MP Brendan O'Hara has resigned as the SNP Westminster group's spokesman for culture, media and sport.
The party confirmed Mr O'Hara had left the role for "personal reasons".
Mr O'Hara, a former BBC and STV television producer, was first elected in 2015 and has also served as the SNP's defence spokesman.
It is not known whether he will remain on the parliament's culture, media and sport committee, where he recently sparked a row between the SNP and data firm Cambridge Analytica.
He has been replaced as the party's culture spokesperson, by Hannah Bardell, the SNP Spokesperson for Small Business, Enterprise and Innovation, who has been the MP for Livingston since the 2015 general election.
