Mr Rowlands was also pressed on why Conservative Senedd leader Andrew RT Davies has removed Ms Jones from her shadow cabinet role but not suspended her from the Conservative group.
He said: “Removing that role in the shadow cabinet is a real significant step.”
Asked if that decision undermined Mr Davies’s postion when he is questioning the integrity and judgement of First Minister Vaughan Gething, Mr Rowlands said: “Andrew RT Davies’s integrity and judgement is absolutely important within this and I’m sure he is reviewing the detail as it comes to light and will take steps as and when it is absolutely necessary.”
A lawyer on behalf of Ms Jones has said in a statement that she “did not receive any formal bullying complaint in relation to any of her staff members”.
They added that she “is satisfied that any allegations in relation to impropriety surrounding expenses are entirely misconceived”.
“Ms Jones’s belief is that these complaints being lodged with the standards commissioner are without foundation.
“As these matters are the subject of ongoing inquiries, it would be inappropriate for Ms Jones to make any further comment.
“Ms Jones has no issue with the or its sources putting these allegations to the police and/or the standards commissioner, which will provide her the opportunity to respond in a formal manner as part of the inquiry should the authorities require it.”
