West London's Polish community is mourning the loss of their parish father, who was onboard the flight which killed Poland's president Lech Kaczynski when it crashed in foggy weather in Russia.
Polish and Russian officials said no-one survived when the aircraft apparently hit trees as it approached Smolensk airport.
Poland's army chief, central bank governor, MPs and leading historians were among more than 80 passengers.
The BBC's Kasia Madera has been talking to the community at St Andrew Bobola Roman Catholic Church in West London about their loss.
