The United Kingdom unilaterally ends its protectorate over Egypt, granting the country nominal independence while retaining significant influence.

A closely contested British general election produces a hung parliament, ending years of single-party dominance in Westminster.

Pope Benedict XVI formally resigns the papacy, becoming the first pope to do so voluntarily in nearly 600 years.
