A video has emerged that saw an incident take place in the House of Commons on Wednesday that initially appeared to show Jeremy Corbyn calling Theresa May a "stupid woman".
The remark came after a tense exchange, in which Corbyn reminded May that the next meeting of the European Council was not until March - two months after the rescheduled meaningful vote is supposed to take place.

He has stated that what he actually said was "stupid people", as May and her supporters jeered him in the House of Commons.
