Theresa May faces Jeremy Corbyn for the first Prime Minister’s Questions since recess, where the Labour leader could run into questions over his alleged meetings with a Communist spy in the 1980s.
Mr Corbyn has dismissed the claims outright and his lawyers have now threatened Tory MP Ben Bradley with legal action for repeating false accusations that Mr Corbyn "sold British secrets to spies".
Brexit is also set to dominate the agenda as more than 60 Tory MPs have signalled they could remove their support if Ms May tried to pursue a softer Brexit.
The powerful European Research Group - led by arch eurosceptic Jacob Rees-Mogg - intervened ahead of crunch Cabinet talks on Thursday where the Prime Minister will strive to unite warring factions over the future relationship with the EU.
It comes as the Government asked the EU to consider granting the UK a longer Brexit transition period than the one proposed by Brussels.
