Coverage of Poland's new prime minister, Jaroslaw Kaczynski, has focused (understandably enough) on the fact
that he is the president's twin brother, a situation for which no-one has
been able to find any precedent. But Poland is large and important
enough to be treated as more than comic relief, and the background to the change of leadership is anything but comic.

The conservative Law and Justice party, to which
both Kaczynskis belong, won the largest share of seats in last year's
Polish election, but failed to put together a coalition with the more
liberal centre-right party, Citizens Platform. Instead, Law and Justice
took in populist parties from both left and right. But Prime Minister
Kazimierz Marcinkiewicz was apparently unhappy with this state of
affairs and had been making fresh overtures to the liberals. According
to The Observer,
for these "unexpected signs of political independence" he was forced to
resign.
