Hundreds of women from across the country gathered in the Nigerian capital this week in support of those leading a push to introduce a quota for female legislators. Currently, only four out of 109 senators and 16 out of 360 House of Representatives members are women. The "Special Seats Bill" would allocate one additional seat for a woman in both the House and Senate in each of the country's 36 states and the Federal Capital Territory. However, this ambitious push has encountered obstacles before. We speak to Brenda Anugwom, CEO of the Nigerian Women's Trust Fund.
