As my colleague Sarah Lyall reports on Twitter, the British royal family announced that the Duchess of Cambridge gave birth to a son at 4:24 p.m. local time in London on Monday.
In a press release sent to news organizations, which pre-empted plans for the official announcement, officials announced that the baby weighs 8lbs 6oz.
The BBC has live video coverage of the scene outside Buckingham Palce, where a formal proclamation of the birth was just placed on a wooden easel.
