Single Parents in UK Parliaments

435 Members of Parliament (67%) have children, and politicians have been single parents across the history of UK governance. However, research has shown that 'women in politics are less likely to be mothers than men in politics are to be fathers', and that women in the House of Commons are generally more likely to be unmarried, childless or have fewer children than men in parliament. New parents who are politicians in the House of Commons do not have access to a formal system of maternity or paternity leave. When they are permitted to be at home, their constituencies are effectively unrepresented. Before 2020, Members of Parliament were expected to return to the chamber in-person to vote when their babies are only a few days old. Proxy voting was formally introduced in 2020 for MPs who had a baby or adopted a child.
