OTTAWA —  Commons Speaker Peter Milliken has threatened to suspend a Conservative MP if he continues making personal attacks against Liberal Leader Michael Ignatieff.

Daryl Kramp received the warning after accusing Ignatieff of hypocrisy on a number of issues.

Milliken told MPs several weeks ago that he would no longer tolerate them using members' statements, which precede question period each day, to engage in personal attacks.

He began cutting off MPs who ignored his ruling.

To avoid being silenced, Kramp and other Tory MPs have taken to issuing scathing assessments of an unidentified politician, whom they identify as Ignatieff only at the very end of their statements -- when it's too late for Milliken to cut them off.

Milliken's warning suggests he's willing to take more drastic measures to put a stop to the personal attacks.
