Nothing is usual about Brexit. It is one of the most important strategic decisions facing the future 10-20 years and perhaps longer.But it's only shutdown 4 working days longer than it would be normally in the conference season. Just happens to be very convenient and they don't like it up 'em !
If that is usual than why the extra 4 days.
As for you SC do you really trust Boris and believe Labour or the LibDems are afraid of elections? You really must be barmy to believe that to be the case.
