TIMESONLINE/ Brief profiles/ Two candidates from Prime Minister Donald Tusk's center-right Civic Platform are fighting to be Poland's next president since the incumbent Lech Kaczynski — the opposition leader's twin brother — seems to be out of the running. They are Radek Sikorski, 47, and Bronislaw Komorowski, 57. Sikorski studied at Oxford, palled-around with Margaret Thatcher and has a glamorous political background. Komorowski ran anti-communist groups and was locked up in internment camps.
