OTTAWA — Sean Casey is publicly calling for Prime Minister Justin Trudeau to step down as party leader as frustration about his leadership mounts inside caucus, making him the second Liberal MP to put his name to a push that reportedly now has the backing of about 30 MPs.

Last week, many media outlets reported that a growing number of Liberal MPs remain frustrated with Trudeau’s leadership and lack of strategy to counter Conservative Leader Pierre Poilievre’s messaging, despite promising to do so multiple times since 2022.
