The Harper government says it plans to support an NDP motion to suspend former Conservative MP Dean Del Mastro, who was convicted last week of Elections Act offences.
The Commons is debating the suspension after Speaker Andrew Scheer found evidence of a breach of parliamentary privilege following the Ontario Court judge's verdict against Del Mastro.
The Canada Elections Act says that MPs convicted of an illegal practice should not sit in the Commons for five years, but Scheer says the House is ultimately responsible for deciding such matters.
The NDP motion would immediately suspend Del Mastro and cut off his salary.
The Conservative government had initially argued that the issue should first go to a parliamentary committee for study.
Government House leader Peter Van Loan says everyone is on the same page on what he call a very serious issue, and says a suspension would be appropriate until all of Del Mastro's avenues of appeal are exhausted.
