Within Poland, former presidents are entitled to lifetime personal security protection by Biuro Ochrony Rządu officers, in addition to receiving a substantial pension and a private office. On 10 April 2010, Lech Kaczyński, president at the time, and Ryszard Kaczorowski, the last president-in-exile although not internationally recognized, died in the crash of the Polish Air Force Tu-154 en route to Russia.[9]
