Parliament in Sierra Leone has unanimously approved legislation that will ensure that one in three of its members, and a third of all local councillors, are women.
The bill will now go to President Julius Bio to be signed into law.
Despite it being a key promise in his 2018 election campaign, it took three years for cabinet to approve the draft.
An earlier version was withdrawn over a technicality.
Currently only 19 of Sierra Leone's 146 members of parliament are women.
