Boris Johnson's partner Carrie Symonds has given birth to a baby boy.
The pair have just announced the arrival of "a healthy baby boy at a London hospital earlier this morning".
Both mother and baby are doing very well.
"The PM and Ms Symonds would like to thank the fantastic NHS maternity team."
Johnson will miss his first PMQs since returning to work, with Dominic Raab deputising for the dispatch box once again.
