Prime Minister Boris Johnson has married his fiancee Carrie Symonds in a secretly-planned wedding at Westminster Cathedral.
The wedding took place in a “small ceremony” on Saturday afternoon, a Downing Street spokesman said.
The spokesman added that the couple would celebrate again with family and friends next summer.
Mr Johnson is the first prime minister to get married while in office in nearly 200 years.
30 guests were invited to the ceremony at short notice – the maximum number of attendees allowed under Covid restrictions in England.
A small number of church officials were involved in preparations for the Catholic ceremony, which was officiated by Father Daniel Humphreys, it said.
Although Mr Johnson has been married twice before, the Roman Catholic Church can allow divorcees to remarry if the previous marriages were outside the Roman Catholic Church.
The last prime minister to get married while in office was Robert Banks Jenkinson in 1822.
Ms Symonds was first romantically linked to Mr Johnson, 56, by the media in early 2019.
Ms Symonds used to work in the Conservative Party press office, which she joined in 2010, and two years later she worked on Mr Johnson’s successful campaign to be re-elected as mayor in London.
She became the party’s head of communications before leaving in 2018 to work in public relations for marine conservation organisation Oceana.
