BBC NEWS: Defiant MSP ordered from chamberThe Scottish Socialist, Carolyn Leckie, has become the first MSP to be expelled from the parliament's debating chamber.
She was shown the door for "disorderly behaviour", after a row with Presiding Officer George Reid.
Just before the start of First Minister's Questions, Ms Leckie tried to raise a point of order about the nursery nurses' strike.
When Mr Reid told her to make her point of order later, she protested and was ultimately told to leave the chamber...
Ms Leckie left with fellow Scottish Socialist Party MSPs Tommy Sheridan, Colin Fox, Rosie Kane and Frances Curran.
When they emerged from parliament which is meeting in its temporary home at The Hub in Castlehill, they were greeted with loud applause by more than 50 striking nursery nurses demonstrating outside.
Ms Leckie said: "I think it is a disgrace that I make a point of order and I am told to wait until the end of first minister's questions to make the point.
"I am not prepared to wait and I have been chucked out of parliament for that.
"I think the shame is on them (MSPs) for not being prepared to discuss the cause of these women in that parliament."
She went on: "I regret that parliamentary procedures are being used to silence the voices of nursery nurses who have been outside conducting a very dignified campaign."
