Prince Andrew made a surprise appearance at the Royal Family's traditional Easter Sunday service but raised eyebrows once again. He arrived at St George’s Chapel with the Princess Royal, his ex-wife Sarah, Duchess of York, and Princess Anne’s husband Vice Admiral Sir Tim Laurence, and an expert has weighed in on what his body language suggested.

His Easter appearance at Windsor Castle is the first time he has been pictured at an official Royal event in a year. After arriving at the chapel, the Duke of York swiftly entered to join the Royal Family, which included King Charles and Queen Camilla.

A body language expert has since examined his entrance, labelling his demeanour as "cocky". He stood with his jacket undone and his "legs splayed in a pose of confidence".

Judi James told the Mirror: "Prince Andrew's body language made this look like his debutante's coming out ball as he performed a kind royal quick-step to appear back in the role of second son to the late Queen.

"While his ex wife Fergie displayed newly-found signals of royal confidence, waving to the crowds, chatting and laughing in her signature animated way and striding forward to greet and chat with the clergy, Andrew waited until the rest of the Firm were in place before suddenly appearing from the gloom of the Chapel doorway where he must have been hiding before making his dramatic entrance."

She added: "Andrew's body language signals were all about a kind of cocky arrogance here. With his jacket undone he positioned himself in the gap in the middle of the group where he stood with his legs splayed in a pose of confidence. He crossed one arm over his belly and his free hand was used to show a stabbing pointing index finger as he chatted with a rather awkward-looking Commander Tim.

"He evaporated back into the gloom of the porch once Charles arrived but that also gave him the option of walking into the chapel close behind the King and Queen, perhaps with Fergie who seemed to have nipped to stand behind him."

Andrew was also spotted speaking with his brother-in-law, Sir Tim, as the family awaited the arrival of King Charles and Queen Camilla. Professional lip reader Jeremy Freeman suggested that while it wasn't entirely clear what was being discussed between the two, Andrew mentioned Prince William and Kate Middleton, who were absent today to spend time with their children. He also seemed to reference a seating plan.
