The country’s former Prime Minister said that, far from deterring other countries from leaving, any attempts to punish the UK will only accelerate the break up of the beleaguered bloc.
Jaroslaw Kaczynski, the influential chairman of the ruling Law and Justice Party, also aimed a torpedo at close neighbours Germany, saying the rest of Europe cannot allow Angela Merkel to sink the EU by refusing to negotiate.
His comments yet again expose the growing division on the continent over how to deal with the fallout of last week’s historic Brexit vote.
Poland is a deeply eurosceptic country and has been dismayed by Britain’s vote to leave the bloc as it feels it has lost its biggest ally in the fight against Brussels federalism.
He also said Brussels should leave the door open for Britain to return to the bloc
Mr Kaczynski has even said the UK should hold a second referendum on the issue of membership, and today reiterated his hopes that other leaders will give Britain “a chance of returning”.
Addressing members of his right-wing ruling party in Warsaw, the heavyweight Polish politician issued a ferocious warning to other member states over the dangers of playing hardball with London.
He also launched a very thinly veiled attack on Mrs Merkel, who sparked consternation across the continent with her decision to consult only the bloc’s founding countries when discussing the fallout of the British referendum.
After the meeting the leaders of Germany, Italy, France, Belgium, the Netherlands and Luxembourg emerged with a tough new line on the UK over the issues of free movement and access to the single market.
