The SNP is to send Nicola Sturgeon flowers following her arrest two days ago.
Depute leader Keith Brown said SNP MSPs agreed to make the show of support at a meeting today.
It comes as Scottish First Minister and party leader Humza Yousaf described his predecessor as Europe’s “most impressive” politician.
He said: “Nicola Sturgeon is the most impressive politician I think we have seen in Europe, she is an asset to our movement, and to our party.
“It’s obviously a difficult time, it’s a very very difficult time for her and a difficult time for our party and personally painful to many of us.”

Mr Yousaf also defended his decision not to suspend Ms Sturgon following her arrest amid accusations he is “weak”.
He said: “The reason I am doing it is because I believe in natural justice. I believe in due process. She was released, of course, without charge.”
Ms Sturgeon on Sunday became the third SNP figure to be arrested as part of the police investigation, which centres on £600,000 crowdfunded from members for an independence campaign.
She was interviewed by detectives for almost seven hours before being released without any charge but pending further investigation.
That mirrored what happened after her husband, former SNP chief executive Peter Murrell, and then treasurer Colin Beattie, were arrested earlier this year.
Mr Brown backed Mr Yousaf’s decision to allow Ms Sturgeon to remain in the party, saying this was in the interests of “natural justice”.
The SNP depute leader added that other cases, where the party’s elected representatives had been suspended while allegations around them were being investigated, involved “different circumstances”.
Mr Brown told BBC Radio Scotland: “I think it’s in the interest of natural justice, which is the principle which Humza, the First Minister, is following.”
