Leszek Kolakowski, Polish anti-Marxist thinker, dies

One of the few 20th Century eastern European thinkers to gain international renown, he spent almost half of his life in exile from his native country.

He argued that the cruelties of Stalinism were not an aberration, but the logical conclusion of Marxism.

MPs in Warsaw observed a minute's silence to remember his contribution to a free and democratic Poland.
