Renault driver Robert Kubica has expressed his shock at the plane crash in which Poland's president Lech Kaczynski lost his life earlier today.
The aircraft carrying the president and nearly 100 other people, including many senior Polish politicians, crashed in fog near Smolensk in Russia while on the way to a ceremony to mark the 70th anniversary of the Katyn massacre during World War II.
"I am deeply shocked and saddened by the news of this tragedy, which is unprecedented for our nation," said Kubica, Formula 1's first Polish driver. "A day of remembrance for the victims of Katyn has become one of deep mourning for the people of Poland.
"I send my sincerest condolences to the families of the victims and my thoughts are with every one of my fellow Poles, who have all been deeply affected by this tragedy."
