Poland commemorates the 15th anniversary of the Smolensk air disaster that killed Polish President Lech Kaczynski, his wife Maria, and 94 other dignitaries and crew. Given the antipathy between the Law and Justice party led by Kaczynski's twin brother, Jaroslaw, and the Civic Coalition led by the current Polish Prime Minister, Donald Tusk; over a decade on from the crash, the anniversary is now publically commemorated by the country's conservatives and religious right.
