The Pauline Latham MP Bill came into effect in 2022. Until recently, children were able to marry at the age of 16 with parental consent, which campaigners warned is a ‘child marriage’. It also leaves girls in particular at risk of being coerced into forced marriages. The law now makes it an offence to marry a child and it applies to both registered marriages and unregistered ceremonial events. Together they discuss how to bring about legal change to advance the rights of women and girls.
