Siddiq has referred herself to a watchdog after allegations she lived in homes tied to her aunt’s ousted regime in Bangladesh

Tulip Siddiq should give up her ministerial responsibility for UK anti-corruption policy, a group of charities has said, amid concerns about her links to the former Bangladeshi regime of her aunt, Sheikh Hasina.

The UK Anti-Corruption Coalition – which includes international groups such as Oxfam, Transparency International and Spotlight on Corruption – released a statement on Monday night urging the Treasury minister to hand over her anti-corruption role.
