Brexit LIVE: Ireland fury at 'unrepentant Brexiteers' as 'threat of trade war looms'

Commons Leader Jacob Rees-Mogg has taunted opposite number, Labour’s Thangam Debonnaire – claiming she is “becoming a Brexiteer” during a sharp exchange in Parliament.

Mr sidestepped Labour questions about whether he called for a hike in National Insurance to fund social care and the NHS to be scrapped at a Cabinet meeting.

At Business Questions, Mr Rees-Mogg said Labour could only call for cuts to taxes like VAT on fuel because the UK had left the “megalithic state” of the EU.

Shadow Commons leader Thangam Debbonaire said: “Perhaps he turns out to be more socialist than he has hitherto let on. Given that, according to the Financial Times, he is now asking his own Government to scrap the National Insurance tax rise, something we have been calling for since it was announced… I wonder – is he about to cross the floor? There is space.”

Mr Rees-Mogg replied: “She thinks that I may be converted to her way of thinking. I think this is wishful thinking, it has to be said, because as her question went on and on it became clearer and clearer that not only is she now referring to taxpayers’ money – a good Tory principle, we always call it taxpayers’ money because we recognise there is no money from anywhere else – but also she is becoming Eurosceptic.

“She has become a staunch Brexiteer because the only way our socialist friends can advocate cutting VAT on fuel is by having left the European Union. If we were still in the megalithic state that she used to so campaign for. We would not be able to cut VAT on fuel.”
