TREASURY minister Tulip Siddiq has referred herself to the Prime Minister’s independent ethics adviser amid controversy over properties linked to her family and her aunt’s political movement in Bangladesh.

She has faced calls for an investigation over reports that she lived in properties in London linked to allies of her relative, the former prime minister of Bangladesh Sheikh Hasina.

Ms Hasina was deposed in August last year following an uprising against her leadership and is now subject to an investigation by the country’s anti-corruption commission.
