Nestle, the world's biggest food company, faces mounting public pressure to halt all business activities in Russia over the country's attack on Ukraine.

Ukrainian President Volodymyr Zelenskyy on Saturday singled out the Swiss company for remaining in Russia in a speech streamed to thousands of demonstrators in Bern, Switzerland's capital, according to media outlets including Bloomberg News and CNN.

"'Good food. Good life.' This is the slogan of Nestle. Your company that refuses to leave Russia. Even now — when there are threats from Russia to other European countries. Not only to us. When there is even nuclear blackmail from Russia," he said.
