UK parliamentarians have voted against adjourning for three days until 3 October to allow Boris Johnson's Conservative Party to hold its annual conference.
The vote, by 306 to 289, came the day after the House of Commons began sitting again following the UK's Supreme Court's ruling that the five week suspension of parliament by Johnson had been unlawful.
Parliament usually has a break during the party conference season, but in this case opposition parties said that it should not be adjourned in the run-up to the Brexit deadline on 31 October.
Before the vote, the Conservatives said their conference in Manchester would go ahead regardless.
The Conservative leader's speech is traditionally on a Wednesday lunchtime - which would clash with Prime Minister's Questions if the House of Commons is sitting.
There have been bad tempered exchanges in the House of Commons since it returned on Wednesday, as divisions over the UK's proposed departure from the European Union intensify.
