Prince Harry lands back in LA just 16 hours after coronation

Prince Harry has landed back in California just 16 hours after his father's coronation.

The Duke of Sussex caught a British Airways flight shortly after King Charles' service finished and arrived at Los Angeles International Airport at about 7.30pm local time (3.30am UK).

This was just 16-and-a-half hours after the coronation commenced at 11am on Saturday.

British Airways flight attendants confirmed to the PA news agency that Harry had been on the flight but said they were not permitted to discuss his trip.

The duke was reuniting with his son after Prince Archie turned four on Saturday, spending the day with his mother, the Duchess of Sussex, at their US home.

Harry's appearance at the coronation marked his first public appearance alongside the royals since he lambasted his family in his controversial memoir Spare.

His book contained claims his father put his own interests above Harry’s and was jealous of his wife.

There was also the incendiary claim his brother, the Prince of Wales, physically attacked Harry during an argument about Meghan.

Buckingham Palace has yet to comment on any of the claims.

At the coronation, Harry was seated in the third row for the crowning of Charles and his stepmother the Queen in Westminster Abbey, and was placed two rows behind William.

Harry chatted to his cousin Princess Beatrice and her husband Edoardo Mapelli Mozzi as he entered the church in the drizzling rain.

He also nodded and smiled to guests as he processed behind them, walking down the nave of the abbey alone.

During the service, as the congregation paid homage to the King, Harry was seen, along with the other royals around him, speaking the words: “God save King Charles. Long live King Charles. May the King live forever.”

His abrupt return to the US meant he did not appear on the Buckingham Palace balcony for the finale of the day, with the Palace confirming earlier he had no formal role at the event.

The coronation celebrations were set to continue on Sunday with big lunches attended by royals and a concert at Windsor Castle.

The King and Queen will join 20,000 members of the public at the coronation concert where, along with other family members, they will see performances by Take That, Katy Perry and Lionel Richie.
