MP Tommy Sheppard seeks SNP deputy leadership
Tommy Sheppard has announced he will stand for the role of deputy leader of the party.
The SNP MP for Edinburgh East said the party had to prepare for a second referendum on Scottish independence and still had "arguments to win".
The current deputy leader, Stewart Hosie, has said he will step down in the autumn.
Mr Sheppard wrote in a blog: "We need to prepare for the challenges ahead, including IndyRef2 when it comes.
"That will be a far tougher test, and we need to be ready."
Others to announce they are running are the party's Westminster leader Angus Robertson and MEP Alyn Smith.
