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.

One of the biggest questions is why someone Siddiq’s ties was given the job of anti-corruption minister in the first place.

The UK’s City minister Tulip Siddiq has quit after she became embroiled in a scandal tied to the ousted Bangladeshi regime, amid warnings that she risked damaging the reputation of the British government.
