Poland is "vulnerable" over the political situation in Crimea and Ukraine, its ambassador to the UK has said.
Witold Sobkow spoke to Andrew Neil on the Daily Politics about his nation's relations with the EU and Russia, and the effect of potential sanctions.
He spoke of the political options open to western nations, but added: "We cannot allow things happening at the barrel of a Russian gun."
