A row has broken out between Nicola Sturgeon and Anas Sarwar over a Scottish Government coronavirus briefing set to take place on Tuesday.
The Scottish Labour leader announced his party had to shift its manifesto launch from Tuesday to Thursday due to an " unscheduled " announcement.
Labour's Scottish Parliamentary election manifesto launch was initially supposed to take place on Monday, however due to the death of the Duke of Edinburgh it was shifted.
It will now take place on Thursday with Sarwar to announce his policies on job creation and economic recovery.
During an appearance on the BBC's Sunday Show, Sarwar said they had planned to move to this coming Tuesday but there was "an unscheduled Scottish Government statement now on Covid, despite us seeking clarification from the government on that".
Sarwar continued: "We've been told to expect a statement from the Scottish Government that was unscheduled.
"So we're having to move our manifesto date again."
He said this was "frustrating" but the party had not been waiting for its manifesto launch to set out its policies on economic stimulus and tackling child poverty.
The next easing of coronavirus restrictions is due to take place on April 26, when indoor opening of hospitality will be permitted.
The Scottish Government said ministers had a duty to communicate public health updates and plans were being kept under review.
At her briefing on Tuesday April 13, Ms Sturgeon said she was "likely" to do another briefing the following Tuesday.
The First Minister tweeted on Sunday: "Tuesday's Covid briefing isn't unscheduled (last Tuesday's was).
"It has been scheduled for weeks - indeed, those watching the briefing I did on 6 April would have heard me signal it."
Sarwar responded with a tweet of his own, saying: "Nicola Sturgeon's own Minister told me that the 'scheduled' briefing this week had been brought forward to last week, so not to expect one.
"I want this campaign to be about ideas - not TV schedules - so we've moved again to ensure we don't clash with a public health announcement."
