Humza Yousaf and Anas Sarwar have clashed over Labour's green energy plans.
The First Minister hit back at the Scottish Labour leader after he was asked if he welcomed the announcement that a publicly-owned energy company would be headquartered in Scotland if Keir Starmer takes power.
Yousaf accused Sarwar of being "far more style over substance" - but Sarwar branded Yousaf "Mr no style, Mr no substance".
