Law and Justice don’t fit into the UK’s political vocabulary. Some UKIP and Tories here, dabs of New and Old Labour there. They were set up by the identical Kaczynski twins, Lech and Jarosław, who found fame in communist Poland as angelic boy film-stars but went on to achieve prominence in the Solidarity movement against communism. Lech Kaczynski was elected Polish president in the 2005 elections, but died with dozens of other top Poles in the 2010 Smolensk air disaster. His brother Jarosław has stayed active as the driving-force behind Law and Justice but has encouraged younger modernising loyalists, most notably Poland’s new President Andrzej Duda, to come to the fore.
