Opposition MSPs are calling for dual mandates to be banned after SNP Westminster leader Stephen Flynn launched a bid to hold seats in both London and Edinburgh.
Conservative MSP Graham Simpson will re-table an amendment to the Scottish Elections (Representation and Reform) Bill that would ban 'double-jobbing' in Westminster and Holyrood.
Under Mr Simpson's proposals, an MP who is elected to Holyrood would have to stand down from Westminster within eight days.
Writing in the Daily Record, he said holding a so-called dual mandate was wrong.
"The Scottish Parliament should be given the opportunity to end this nonsense ahead of 2026 and I will give it that chance," Simpson wrote.
"I will re-table my amendments on this so that parties can do the right thing and show that MSPs think the practice of double jobbing is no longer acceptable."
Mr Flynn has faced criticism from within the SNP and opposition parties after announcing his intention to stand for the Aberdeen South and North Kincardine seat at the 2026 Holyrood election, whilst aiming to hold his Westminster seat until the next general election in 2029.
Mr Flynn and SNP colleagues previously criticised former Scottish Tory leader Douglas Ross for holding two seats at once.
