Speaker boots 100th Labor MP

Bronwyn Bishop has scored a century, booting out her 100th Labor MP.

The Speaker's auspicious achievement came during a rowdy post-budget question time as Labor MPs launched a barrage of questions about the impact of the budget.

Labor backbencher Terri Butler had been warned for interjecting while Treasurer Joe Hockey was speaking.

Her ejection came after one interjection too many as Prime Minister Tony Abbott spoke about the budget.

Manager of opposition business Tony Burke noted Ms Butler was the 100th Labor MP ejected from the house, against nil coalition members.

"If you had 100 members you'd be in government and sitting on this side. You simply have some recurrent offenders," Mrs Bishop replied.

Under the House of Representative standing orders, the Speaker can eject disorderly members from the chamber for an hour.
