If passed into law, the Family Law (Property and Maintenance) Bill will (inter alia) abolish the common law duty of a husband to maintain his wife. The bill was introduced by Rob Marris, Labour MP for Wolverhampton South West, to give spouses greater equality and (in his words) to remove "discrimination against men".
