Last-minute parliamentary wrangling on Monday delayed a vote by Canadian legislators on a non-binding motion to back Palestinian statehood, an idea that looked set to deepen splits inside the ruling Liberal Party, Reuters reports.

The original motion was drawn up by the minority left-leaning New Democrats (NDP), who are helping keep Prime Minister Justin Trudeau’s Liberals in power and are unhappy by what they see as his failure to do enough to protect the civilian population in Gaza.

The initial version called on Canada to “officially recognize the State of Palestine” — a step that no member of the Group of Seven industrialized nations has taken.

After back room negotiations between the NDP and the Liberals, that wording was dropped in favor of language calling on the international community to work toward the establishment of a Palestinian state as part of a two-state solution.

But Liberal and opposition legislators in the House of Commons complained they had had no notice of the new wording and demanded the chance to debate it. Proceedings were suspended, and it was unclear when they would be resumed.
