Prince Edward paid a visit to his brother over the Easter weekend as he is worried about the 66-year-old's mental state, according to the Daily Mail.

The visit by Edward, alongside his wife Sophie, was described as "a brotherly welfare check" amid a turbulent time for Andrew.

The former Duke of York was whisked away to the Sandringham Estate after being served notice on his last property, Royal Lodge in Windsor.

It came at the same time as he was stripped of his royal titles, as his friendship with the paedophile Jeffrey Epstein continued to cause controversy for his family.

He was then arrested in February at his temporary home in Norfolk on suspicion of misconduct in public office.

Thames Valley Police said he was released under investigation, and he was pictured slumped in the back of a car leaving Aylsham Police Investigation Centre.

Sources close to Edward have described him as "deeply unsettled" and worried about his brother's physical and mental state.

"Edward and Sophie had dinner with Andrew one night over the weekend and they talked things through," a source told the Daily Mail.

"They are worried about his fragile state of mind."

It is understood the pair usually reside at Wood Farm over Easter but had to stay elsewhere on the estate during the visit.

The only response from King Charles following his brother's arrest is the comment he issued on the day.

"Let me state clearly: the law must take its course," he said.

It is believed the Prince and Princess of Wales support the hard line the King has drawn.

On Monday, it is thought that Andrew moved into his permanent abode at Marsh Farm after living at Wood Farm on the estate since February.
