Jaroslaw Kaczynski, twin brother of late Polish President Lech Kaczynski, enters the Presidential Palace in Warsaw after his brother's casket was carried inside by Polish Army officers on April 11, 2010. The body of Poland's late president arrived back home on April 11 as his stunned nation mourned the loss of much of its elite in a jet crash in Russia that investigators said was not due to technical faults. Draped in a red and white Polish flag, the coffin bearing Lech Kaczynski was carried onto a red carpet at Warsaw Airport, where it was met by his identical twin brother Jaroslaw, a former premier, and a presidential guard of honour.
