In Coventry, 21 women of Indian origin booked what were supposed to be routine appointments with their local GP. Little did they know that these appointments would result in them becoming subjects of a controversial medical experiment, in which they were given chapatis laced with radioactive components.

Political parties in Japan are boosting their support to get more women into office. The country’s ruling party and opposition party are both offering financial incentives- pledging a million Japanese Yen, about £5400, in aid for each new female candidate. And many would say the country sorely needs more women in politics- with the World Economic Forum showing only 10% of the country’s parliamentary positions are held by women. Rei Murakami is the President of the Murakami Foundation, and has set up a politics training school with this goal in mind. Hanako Montgomery is a Tokyo-based journalist.
