Jets to Ukraine decision 'not easy' says Poland president

One of Ukraine's closest allies has cast doubt on whether it would be able to supply President Volodymyr Zelenksy with the fighter jets he says are needed to win the war with Russia.

Poland's President, Andrzej Duda - speaking exclusively to Sunday with Laura Kuenssberg - said sending F-16 aircraft would be a "very serious decision" that was "not easy to take".
