The Scottish Government's Brexit Secretary told MSPs the EU vote "unequivocally" should take place and the SNP is ready to contest them vigorously.
"Unequivocally I believe they should happen - I would want them to happen," Russell told Holyrood's Constitution committee today.
"I think the EU's position is that they really have to happen if things go beyond the 12th. So I would hope they would happen and we will contest them very vigorously."
"I am absolutely confident that Scotland's electoral administrator's will be prepared and the moment that they are told this is going to happen, they will do so efficiently and effectively.
A decision must be made by April 15 on whether the UK will take part in the European elections, Mr Russell added.
European elections are organised by the UK as the member state.
