A plane carrying the body of Polish First Lady Maria Kaczynska, who was killed in an air crash in western Russia, landed in Warsaw on Tuesday morning.
A brief ceremony was held at the airport, similar to that for the return of late President Lech Kaczynski's coffin on Sunday.
The First Lady's coffin will be transported to the presidential palace to be placed next to that of her husband in a presidential chapel.
Following a family ceremony, the couple's coffins will be placed in the Column Hall of the presidential palace for public viewing.
The presidential couple, together with more than 90 others, died in an air crash in Smolensk, western Russia, on Saturday morning.
Senate Speaker Bogdan Borusewicz said Tuesday that a state funeral will most likely be held in Warsaw on Saturday, to morn those who died in the crash.
On the same day, Presidential Minister Jacek Sasin said the burial of the presidential couple may take place on Sunday. He added that he should not reveal where the couple will be buried at the moment, "although the family has already made the decision."
