Prime Minister Boris Johnson's fiancée Carrie Symonds gave birth to a 'healthy' baby boy at a hospital in London today.
The couple's spokesman said they were 'thrilled' to announce the birth which took place early this morning, adding: 'Both mother and baby are doing very well.'
The news comes as something of a surprise, with Miss Symonds having been expected to give birth in the summer, although a date was never confirmed.
