Those involved 'would have known there was a division'

A House of Commons spokesperson said: "Both divisions proceeded as normal last night, with division bells and the usual audio/visual indications on the hundreds of monitors around the estate.

"The division bells have been tested this morning and are working correctly."

The spokesperson added: "There would have been a lot of activity there around those (meeting) rooms.

"I think it would have been clear that there had been a division on and those involved would have known there was a division on as well."
