An MSP could be struck off as a registered midwife after being convicted over an anti-nuclear protest.
Carolyn Leckie was a midwife before becoming an MSP
The Scottish Socialist Party's Carolyn Leckie is currently being investigated by nursing's professional body for alleged "misconduct".
She was arrested during a demonstration at Faslane naval base and has unsuccessfully appealed a breach of the peace conviction.
The Nursing and Midwifery Council may now decide to strike her off.
The controversial MSP has refused to pay a £100 fine over her conviction and is due to appear in court on Thursday to face a charge of non-payment.
The Nursing and Midwifery Council said it has received allegations of "misconduct" against her as a result.
It now has to decide if her conviction amounts to "conduct unworthy of a registered midwife".
Ms Leckie, who worked a midwife before becoming an MSP, said it would be an "affront to democracy" for political activity to undermine her professional standing.
And she said she is confident officials can be persuaded not to strike her off as a midwife.
In a statement, Ms Leckie said: "I won't be paying the fine, to do so would be an indication that I had done something wrong.
"I was protesting against Britain's weapons of mass destruction, I regard that as a duty not a crime."
