Former president Lech Walesa thinks the decision of Jaroslaw Kaczynski – twin brother of the late Lech Kaczynski who died in the Smolensk air disaster – to stand in June's election is a mistake.

The Solidarity icon criticised the decision of the Law and Justice party leader to run in the lections will mean certain defeat.

“Putting him up [for election] is wishing him ill. I’m absolutely convinced of it.  In spite of everything, we were once on one side of [the struggle with the communists] and we had our successes. So I’m not against him, but this campaign means defeat and why should anyone wish him that,” he said.
