The Scottish National Party's business spokesperson said the people of Scotland must choose between "Britain and Brexit" or "Scotland and Europe".
Drew Hendry appeared on the breakfast show to discuss Nicola Sturgeon's announcement that she wants to hold a second Scottish independence referendum by 2021.
"Everybody has seen the Brexit situation play out. Even the most ardent opponents of independence agree that the Westminster system doesn't serve Scotland's interests," Mr Hendry told talkRADIO's Julia Hartley-Brewer.
"We have seen cross-party votes in the Scottish Parliament ignored, the MPs that represent Scotland ignored in this process, and we have seen the 62 per cent remain vote in Scotland ignored by Westminster."
The MP for Inverness, Nairn, Badenoch and Strathspey added that being an independent country would "better match" Scotland.
"It has got to the stage now where something has to be done to give the people of Scotland the choice between the future with Britain and Brexit, or Scotland and Europe.
"Devolution in its current form is clearly inadequate in protecting Scotland's interests, particularly when this UK government ride roughshod over the established principles of the 20 years of devolution."
