If there are no statements or emergency questions then we are looking at around 8:30pm start of voting although this is most likely not going to be on the actual deal as it's probably going to be certain that amendments will be pushed to a vote and it's expected to be that either amendments A, I, K, B, F are pushed to a vote. So yeah the actual vote isn't likely until or after 10pm.
You have to wonder if Channel 4 will simply rip up their schedule for the night as the EPG info suggests that they will be covering the actual vote. As for BBC One and ITV, I think they will extend the 10pm news anyway whether the vote happens before or after 10pm. It'll be a certainly interesting night on Tuesday and the days after that on the presentation and presenting side anyway.
EDIT: Correction, the debate finishes at 7pm but never the less, still plenty of votes to get through.
