Andrew Mountbatten-Windsor has made his first public outing since moving to Sandringham to watch his sister-in-law Sophie in a carriage driving competition.

The disgraced former prince was seen driving his Land Rover Defender away from the annual Sandringham Horse Driving Trials on the King’s royal Norfolk estate.

Andrew left straight after the Duchess of Edinburgh’s event finished on Sunday morning – with his brother Prince Edward also watching from the sidelines.

The ex-Duke of York, who now lives on the Sandringham estate at Marsh Farm in Wolferton, has rarely been spotted in public since his arrest on February 19.

He moved out of his Royal Lodge home in Windsor earlier that month on February 2 to move to Wood Farm while renovations were carried out on Marsh Farm. 

Edward, who was casually dressed in white trousers and an open-necked polo shirt while supporting his wife on Sunday, was seen leaving the event soon after Andrew.

Sophie, who was wearing a long cream jacket, navy blue flowery skirt and a straw boater, stayed for the afternoon and later handed out prizes to the winners.

Sophie and Edward are thought to have been staying at the Wood Farm residence near Andrew’s house, while the three-day competition was taking place.

Their daughter Lady Louise Windsor, who is a student at the University of St Andrews, has previously competed in the event but was not present on Sunday. 

The Sandringham trials were started in 1982 by Prince Philip, who wanted to bring one of his favourite sports to one of his favourite places.

Andrew was arrested on suspicion of misconduct in public office on February 19 and interviewed under caution before being released under investigation.

Detectives at Thames Valley Police are also considering allegations of sexual misconduct in their inquiry.

Andrew served as the UK’s special representative for international trade and investment from 2001 until 2011, when he stepped down amid controversy over his friendship with paedophile financier Jeffrey Epstein.

He has denied any wrongdoing over his links to the convicted sex offender.
