What Is The Queen's Announcement, And What's Happening At Buckingham Palace Today?

Here's the likelihood of theories flying across social media.

Speculation surrounding a mystery meeting of the Queen’s household staff at Buckingham Palace on Thursday reached fever pitch - before the real reason was revealed.

Before the confirmation, nobody was certain as to the reasons behind the gathering, described as an emergency by senior Royal reporters.

Buckingham Palace did not comment on the meeting when contacted by HuffPost earlier on Thursday morning. The Palace later announced Prince Philip would no longer carry out Royal duties.

But here we assessed some of the other theories which gained most attention.

Is Prince Philip Dead? No, He’s Not

The death of the Queen’s consort Prince Philip, 95, would likely be announced in a similar way to the passing of the Monarch themselves - following Royal protocol.

According to an account of that protocol, Operation London Bridge, by Guardian writer Sam Knight, Buckingham Palace would wait until the following morning, rather than making an announcement overnight.

But this simply fuelled speculation over the cause of Thursday’s all-staff meeting at the Palace amid some reports that the Queen’s private secretary would make an announcement at 8 am.

And according to Knight’s account, the BBC would be among the first to confirm Royal news relating to health.

Yet the broadcaster’s flagship Radio 4 Today programme on Thursday led with news of the “bad tempered television debate” between French presidential contenders Marine Le Pen and Emmanuel Macron.

In perhaps a sign of its relative lack of importance, the all-staff meeting garnered just one news entry on the BBC website placed halfway down its front page.

The Palace later confirmed Philip would no longer carry out his royal duties.

Buckingham Palace renovations

Buckingham Palace is in dire need of extensive repairs, could this lie behind Thursday's all-staff meeting

A ten-year programme of works commenced last month and is due to replace ageing facilities, including those presenting a fire risk to the 300-year-old palace. 

And as the pictures, swipe below, suggest - the work is sorely needed.

Disrepair And Danger: Buckingham Palace Renovations

Dickie Arbiter, a respected Royal commentator, said Thursday’s meeting “could well be about the Buckingham Palace refurbishment”.

But does the gathering signal a re-location to allow renovations to go ahead as planned? 

Any move would need to be announced to staff members and an all-staff gathering would reflect the huge task ahead.

It would be the first time a Monarch has left Buckingham Palace since Queen Victoria designated it her official residence in 1837.

But it has long been rumoured that renovations will require the Queen to leave London for one of her other palaces - most likely Windsor, the Royal’s weekend home, 21 miles west of the capital.

A royal source told the Daily Telegraph in 2015: “One option is for the Palace to be vacated. The other option would be to do it in sections and move people from one section to another.”

Either way, renovations would pose the sort of logistical challenge to the Royal staff that might require an all-staff meeting of the kind called on Thursday morning.

Sky News presenter Kay Burley sparked wild speculation that Thursday’s meeting was related to a wedding.

She wrote on Twitter simply: ‘Church bells?’ The Daily Mirror’s 3am reported fans were “praying” the all-staff meeting signalled a union between Prince Harry and Meghan Markle.

But, alas, that announcement would come via Kensington Palace, not Buckingham Palace - and even the Duke of Cambridge’s wedding didn’t elicit an all-staff meeting of the kind called on Thursday.
