Meghan Markle and Prince Harry attend final royal outing at Commonwealth Day service

The Duke and Duchess of Sussex have wrapped up their stunning farewell tour, just months after announcing their exit from the royal family.

Meghan Markle and Prince Harry have arrived at their last official engagement as senior members of the British royal family.

The couple joined the Queen at the Commonwealth Day service at Westminster Abbey, which takes place on the second Monday in March.

In contrast to last year, Harry and Meghan, along with Kate Middleton and Prince William, did not join Her Majesty’s procession through Westminster Abbey.

Instead, they were shown to their seats - with tradition dictating that sixth-in-line Harry sit with Meghan in the second row of seats behind the Queen, Charles, Camilla, William and Kate during the service - rather than waiting for Her Majesty’s arrival and walking in behind her.

And in a last minute change, Prince William and Kate Middleton also did not join the 93-year-old monarch in the procession.

A source said the sudden amendments were made on Sunday - the day before the event, despite the Order of Service already having been signed off and printed.

Prince Charles and Camilla, clergy, Prime Minister Boris Johnson and the Commonwealth Secretary General took part in the procession instead.

Kensington Palace and Buckingham Palace have not commented as to why the switch was made.

Kate wore a red coat dress from her go-to designer Catherine Walker & Co with a matching hat, red velvet clutch and heels.

The royal family reunion was four months in the making, as the two couples hadn’t been seen together since they stepped out for Remembrance Day events in November.

The royals and other guests listened to international boxing champion and Olympic gold medallist Anthony Joshua deliver a reflection, before singers Alexandra Burke and Craig David performed to the 2,000-strong congregation.

About 45 minutes before the royals arrived, Cameroon protesters tried to storm the security fences outside Westminster.

Police later confirmed two people had been arrested at the scene.

Today’s service marks the last joint appearance the Duke and Duchess of Sussex will be making before stepping back as senior royals and starting fresh in Canada, where they aim to become “financially independent”.

It is also the first time Meghan and Harry have reunited with Prince William and Kate Middleton since the Megxit fiasco, and amid long-running reports of a family feud.

Prince Charles and Camilla are also in attendance.

The Sussexes are closing their Buckingham Palace office on April 1 and heading back to Canada, where they wish to raise their first child, Archie, away from the spotlight.

The couple has had a tight schedule in the past few days during their “farewell tour”, starting at the Endeavour Fund Awards on Friday, where the duchess wore a striking blue Victoria Beckham dress.

Meghan then made a private visit to the National Theatre, of which she is a patron.

On Saturday, Harry attended the official opening of the Silverstone UK Experience Museum, while Meghan surprised kids at a school in East London for International Women’s Day, where a schoolboy managed to steal a kiss before telling his peers, “She really is beautiful, innit?”

That evening, the Sussexes received a resounding standing ovation at the Royal Albert Hall as they entered the royal box for the Mountbatten Festival of Music, where Meghan stunned in a red Safiyaa cape dress.

While it wasn’t in their official public schedule, Meghan and Harry attended church at the Royal Chapel of All Saints in Windsor on Sunday, alongside the Queen.

It was the first time Meghan had seen the Queen since they announced news on January 6 of their decision to step back the royal family.

The Commonwealth Day service is attended by heads of government and representatives of the 54 countries of the Commonwealth.

In recent years the Service has been broadcast live by the BBC and has attracted contributions from Ellie Goulding, Sir Richard Branson, and Nobel Peace Prize laureates, Malala Yousafzai and Kailash Satyarthi.
