Jacob Rees-Mogg referred to as 'Moggy' by Labour's Geraint Davies

Swansea West Labour MP Geraint Davies has apologised after Speaker John Bercow told him off for referring to Conservative MP Jacob Rees-Mogg as "Moggy" during a Commons debate about the EU referendum.

MPs customarily refer to each other during debates by the name of their constituencies.

Mr Davies said he could not remember the full name of the Tory backbencher's seat of North East Somerset.
