The head of the Queen's household has banned royal servants from bringing their dogs into work due to fears over 'security'.

The Lord Chamberlain has ended the tradition, thought to be hundreds of years old, across all of the monarch's official residences over concerns of safety and 'hygiene'.

Staff at Buckingham Palace, Windsor Castle and Sandringham House in Norfolk, have all been told their beloved pooches will no longer be welcome in the office.

A source told the Express: 'Palace staff are up in arms about it.

'It's an odd decision considering the Queen and her family are such dog lovers. Obviously it doesn't affect the royal corgis.'

It is not clear whether Clarence House or Kensington Palace has adopted the ban.

The Duke and Duchess of Cambridge live with their family's beloved cocker spaniel Lupo at the palace.

While Prince Harry and fiance Meghan Markle live in Nottingham Cottage in the palace grounds with American actress's beagle, Guy.

A Buckingham Palace spokeswoman said: 'Decisions on allowing staff to bring dogs are taken on a case by case basis, taking into account all practicalities, the potential impact on the fabric of buildings and the owner's individual circumstances.'

The queen currently has two corgis and two corgi-dachshund crosses, after stepping in to take care of her gamekeeper's dog when he passed away.

Her Majesty looked after the Corgi and Bichon Frise belonging to former Sandringham gamekeeper Bill Fenwick as he became too ill to walk them.

But in January 2017, Mr Fenwick died aged 95, two years after his wife Nancy, who was known as the 'Keeper of the Queen's Corgis'.
