The SNP and Scottish Conservatives have announced they are postponing their spring conferences due to coronavirus.
Scottish Tory leader Jackson Carlaw said the party’s conference, due to take place in Perth in mid-May, will now be moved to later in the year.
An upcoming party convention this month has also been cancelled and planned campaign days have been delayed until official public health advice changes.
Mr Carlaw said the party is considering expanding a one-day conference planned for the autumn instead.
Meanwhile, SNP members have received an email alerting them to the postponement of their party’s conference, which was due to be held in Edinburgh in June.
The email states the party’s national assembly meeting this weekend will also not take place “for the foreseeable future”, and adds: “Member safety is our priority and it is crucial to us to minimise risk to our colleagues and others on this occasion.”
Announcing the postponement of the Scottish Tory conference, which would have been his first as leader since replacing Ruth Davidson, Mr Carlaw said: “It’s become clear we have no option but to postpone the party conference that was planned for May.
“The same goes for a party convention that was due to go ahead later in March.
“The wellbeing of our staff, party members and others who would have attended conference has to be paramount.
“We’re also aware that such a large-scale event involving senior (UK) Government ministers also requires the presence of emergency services, and that’s not what they need to be doing while this pandemic unfolds.
“The conference will take place at some point, and one option we’re considering is to extend a planned one-day event due to go ahead in the autumn.
“We’ll be providing plenty of notice about that as and when the final decision is made.”
On Thursday, the Scottish Greens became the first Scottish party to cancel their spring conference over coronavirus fears.
Ross Greer MSP, the party’s executive co-chairman, said: “Due to the ongoing coronavirus situation, the Scottish Greens executive committee has taken the decision to cancel our upcoming conference.
“The health and wellbeing of our members and the public is our primary concern and it is with that in mind that we have taken this decision.”
