Labor will ramp up its criticism of Speaker Bronwyn Bishop on Wednesday by asking Coalition MPs to support a parliamentary motion calling for the Speaker to be impartial and not attend party room meetings.

On Wednesday, manager of opposition business Tony Burke will introduce a motion into the House of Representatives on the importance of Speaker independence.

The motion will ask the House to endorse past statements by Coalition MPs – including Prime Minister Tony Abbott – on Speaker impartiality.

It will also ask MPs to endorse "a practice whereby the Speaker refrains from attending his or her party room".
