British Prime Minister David Cameron has compared Russia to Nazi Germany over Moscow’s actions in Ukraine ahead of meeting with Vladimir Putin on Saturday at the G20 summit in Australia.

MOSCOW, November 13 (Sputnik) – UK Prime Minister David Cameron has likened Russia to Nazi Germany over Moscow’s actions in Ukraine ahead of his meeting with President Vladimir Putin, The Daily Telegraph reported Friday.

“Russian action in Ukraine is unacceptable. We have to be clear about what we are dealing with. It is a large state bullying a smaller state in Europe … We have seen the consequences of that in the past and we should learn the lessons of history and make sure we don't let it happen again,” the prime minister said in reference to World War II, according to the newspaper.

It is not the first time the British politician made such a controversial comparison. In September, Cameron told EU leaders at a summit in Brussels that the West risks making similar mistakes in appeasing the Russian president over Ukraine as Britain and France did with Adolf Hitler in the run-up to World War II.

The British prime minister is expected to meet Putin on Saturday at the G20 summit in Australia, the first such meeting between the two since the Ukraine crisis erupted.

Western countries have been accusing Russia of escalating tensions in eastern Ukraine, arming independence supporters and sending its troops to the volatile regions. Moscow has labeled the claims as groundless.
