Joe Biden said on Wednesday that Britain was the United States’ closest ally and friend during his first face to face meeting with Rishi Sunak since he became Prime Minister. The pair met on the sidelines of the G20 summit in Bali with Mr Sunak saying that the partnership between the two nations was unique and that there values and interests were aligned.However, the meeting was overshadowed by news that missiles hit a rural area of Poland, killing two people.According to reports, the missiles struck a grain factory near the Ukrainian border on Tuesday.It is unclear if they were deliberately fired into Polish territory or if they accidentally strayed off course.Before meeting the Prime Minister Mr Biden said it was “unlikely” that the missiles had been fired from Russia but warned that an investigation needed to take place first.
