The £1bn a month cost to taxpayerspublished at 12:01 British Summer Time 2 October 2019
Reality Check
Boris Johnson has told his party conference that delaying Brexit beyond 31 October would cost £1bn a month.
The problem with this figure is that if there is a Brexit deal, as Mr Johnson says he wants, it will include payments to the EU, currently expected to be about £33bn.
That figure includes budget contributions until the end of a transition period.
So unless there is no deal, contributions to the EU budget will have to be made anyway.
The figure also ignores money coming back to the UK - you can read more about it here.
