A smiling Rachel Reeves makes a surprise appearance as the Prime Minister Keir Starmer unveils his 10-year plan for Britain's National Health Service (NHS), a day after the UK's finance minister was seen in tears in parliament, causing markets to tumble amid speculation over her future. A spokeswoman for Starmer told reporters later Wednesday that Reeves had his "full backing", while a spokesman for Reeves said she had been upset due to a "personal matter".
