King Charles reportedly has ‘made it clear’ Prince Andrew is no longer welcome at Buckingham Palace.

The new monarch has banned his younger brother from using the royal residence as a corresponding address, palace sources claim.

A source told the Sun: ‘Any presence at the Palace is officially over.

‘The King has made it clear. He isn’t a working royal. He’s on his own.’

Andrew stepped back from royal public duties following accusations of sexual assault from Virginia Giuffre and scrutiny over his friendship with convicted sex offender Jeffrey Epstein.

He strongly denied the claims and reached an out-of-court settlement with her in February.

The disgraced royal was recently said to be ‘furious’ at being stripped of taxpayer-funded protection from the Metropolitan Police.

Andrew was believed to have written to both the Home Office and Scotland Yard to complain.

His security will be replaced by private security guards which will cost up to £3 million a year, The Telegraph reports.

It had been theorised that the bill would be picked up by Charles, as Andrew is thought to have no regular income.

Buckingham Palace and the Duke of York has been contacted for comment by Metro.co.uk and declined to comment.
