Poland air crash ceremony marked by divisions

Poland has marked the first anniversary of the plane crash in western Russia that killed President Lech Kaczynski, and 95 others but the occasion is marked by deep divisions.

Lech Kaczynski twin brother, Jaroslaw, has condemned the government's handling of the affair, and held his own rival events.

The BBC's Adam Easton says that after initially bringing the country together, the crash is now bitterly divisive.
