NDP Leader Jagmeet Singh says he has not revealed any "red lines" to the Liberals that would prevent his caucus from voting to support the minority government's legislation, but his MPs are prepared to withhold their votes to push the Liberals on issues including climate change and paid sick leave. He made the comments after the NDP's first postelection caucus meeting, where he says MPs gave feedback on the national campaign and ways to win more seats next time.
