So, this means that the Emergencies Act vote will fail then.
I wonder if Singh is doing this to save Trudeau from making a worse mistake, like TPTB are realizing invoking it was a shit idea that made things worse for them, but they couldn't let Trudeau visibly back down, so instead they have Singh withdraw support so the motion fails without Trudeau having to compromise or change stance. Maybe I'm being paranoid, but the NDP has always blindly backed every move of the Liberals before, so I can't help but feel that it's still true.
