The voting will start at 1900 GMT

Theresa May will lose today's meaningful vote despite a desperate last-minute attempt to alter the text of the joint agreement. Still, the depth of the loss will be important.

The January 15 vote was 432-202 with 1 abstention. This one could be closer but it depends on whether the ERG and DUP vote it down or abstain. I'd estimate that the over-under is a 100-vote loss.

The voting will start at 7 pm GMT, which is about 5 hours from now and, 4 pm ET. There will be some amendments first and they take 15 minutes each.

Update: The speaker has not selected any amendments to be put to a vote so the vote should be shortly after 1900 GMT.
