English, when asked on Monday, was unclear on whether Barclay would also take up his positions on select committees. He is deputy chairman of the Education and Science, and Primary Production select committees, both of which will meet this week.
Barclay's workload since his decision to retire has come under scrutiny in recent weeks.
After appearing to take some time off after the allegations resurfaced, and police relaunched their investigation, Barclay posed for a picture on his Facebook page on Tuesday with a caption indicating he was "working on constituent issues".
Since then the page has been flooded with pictures of Barclay posing with various projects and a flashback photo from his childhood.
