Treasury minister Tulip Siddiq has resigned, after growing pressure about allegations of corruption linked to her aunt, the deposed prime minister of Bangladesh.

Treasury minister Tulip Siddiq has resigned after growing pressure over an anti-corruption investigation in Bangladesh. She had referred herself to the prime minister's standards adviser, Sir Laurie Magnus, after questions about links to her aunt, who was ousted last year as Bangladesh's prime minister.
