Polish EU chief Donald Tusk warns there is a ‘deadly serious’ risk his home country could be the next to leave the bloc.

Mr Tusk fears a bitter feud with Brussels over reforms to Poland’s judicial system could push it out – in a so-called ‘Polexit’.

The EU Council chief said he drew parallels with Britain’s decision to leave the EU and clashes between Poland’s ruling Law and Justice (PiS) party and Brussels.

He said former prime minister David Cameron had not meant to take Britain out of Europe and claimed Poland could also end up leaving by accident.

Mr Tusk served as Poland’s prime minister from 2007 to 2014 and has long been a rival of PiS leader Jaroslaw Kaczynski.

During a press conference in Warsaw, Mr Tusk: ‘The matter is dramatically serious and the risk is deadly serious.

'I would like those who are doing everything to cause a so-called Polexit to stop.’

He added that ‘even if Kaczynski does not have a plan to lead Poland out of the [EU], the appearance of the term “Polexit” in political discussion is already dangerous’.
