Shocking Royal News: Will Kate Middleton Grace the Buckingham Palace Balcony at Trooping the Colour? Rebecca English Reveals Explosive Details on PALACE CONFIDENTIAL!”

A royal expert has said a ‘big question’ remains as to whether the Princess of Wales could appear on the Buckingham Palace balcony at Trooping the Colour on Saturday.

Kate, 42, who is undergoing cancer treatment, did not attend the Colonel’s Review on June 8 – which is the traditional rehearsal for the sovereign’s official birthday parade.

But Rebecca English, The Daily Mail’s Royal Editor, suggested to this week’s Palace Confidential that an appearance from the royal at this weekend’s event in London, should not be completely ruled out amid ‘persistent rumours’ she might appear on the balcony.

‘What’s very interesting, is that when I’ve asked both Kensington Palace and Buckingham Palace about it this week, it’s been not saying a word,’ said the expert.

She continued: ‘I mean look, if she is there. Fantastic. People will be delighted to see her. If she isn’t, don’t read anything into it because she never said she would be. I think it will be a bonus.’

Earlier in the show, Rebecca had explained how the King, 75, who is also undergoing cancer treatment, is set to attend Trooping the Colour.

‘It’s great that [the King] is going to there,’ she said. ‘Queen Camilla will be there, we’ll have Prince Edward, Princess Anne, Prince of Wales on horseback, we’ll have all the pomp and pageantry, but it’s just going to be in a slightly more comfortable way for him.’

‘For me, actually, the big question is whether the Princess of Wales will be there on the balcony afterwards, that is a rumour that just hasn’t gone away over the last few weeks.

‘She’s made very clear, “look when my doctors say I’m ready to dip my toe back in, I will happily do that”, but it’s certainly been a persistent rumour.

‘I spoke to somebody a few weeks ago and said “what do you think?” And they said, “I wouldn’t count on it”.

‘But it hasn’t gone away, and what’s very interesting, is that when I’ve asked both Kensington Palace and Buckingham Palace about it this week, it’s been not saying a word… I think watch this space.’

MailOnline has contacted both Kensington Palace and Buckingham Palace.

Rebecca’s comments come after the Daily Mirror reported last month that the Princess is thought to be considering walking onto the famous balcony if she is feeling well enough.

Kate continues to stay away from public royal duties during her chemotherapy while resting at home, and will only return when doctors give her the all-clear.

Last Saturday, Kate apologised for missing out on a key rehearsal for Trooping The Colour.

The Princess wrote a letter to the Irish Guards, who are presenting their colours to the King this year, saying: ‘I hope I am able to represent you all very soon’.

Kate missed out on what would have been her first Colonel’s Review. The event is a dress rehearsal for Trooping The Colour and would have seen her take the salute as the new Colonel-in-Chief of the Irish Guards.

Kate’s letter in full

I wanted to write and let you know how proud I am of the entire regiment ahead of the Colonel’s Review and Trooping the Colour.

I appreciate everyone trooping this year has been practising for months and dedicating many hours to ensuring their uniforms and drill are immaculate.

Being your Colonel remains a great honour and I am very sorry that I’m unable to take the salute at this year’s Colonel’s Review. Please pass my apologies to the whole regiment, however, I do hope that I am able to represent you all once again very soon.

Please send my very best wishes and good luck to all involved.

Insiders have long emphasised that every cancer‘journey’ is individual and believe speculation over whether Kate will attend key events such as Trooping create unnecessary pressure at a time when she has asked for space and privacy.

The Colonel’s Review comes before the King’s official birthday celebrations on Saturday June 15, including their traditional Buckingham Palace ­balcony appearance.

It is identical to The King’s Birthday Parade, with the exception that some additional mounted officers ride on the latter.

The Irish Guards have responded to the Princess’s letter on Twitter, writing: ‘The Irish Guards were deeply touched to receive a letter from our Colonel, Her Royal Highness, The Princess of Wales this morning.

‘We continue to wish Her Royal Highness well in her recovery and send her our very best wishes.’

Meanwhile Buckingham Palace did confirm previously the Daily Mail’s exclusive story in March that King Charles planned to attend Trooping and review the soldiers from a ­carriage, on doctor’s advice, with Queen Camilla.

He has previously taken part on horseback but it has been deemed prudent, given the length of the ceremony and the unpredictable weather, for him to be seated in an Ascot landau.

His Majesty is still undergoing treatment for his own unspecified ­cancer diagnosis.

He has now been given permission by his doctors to undertake more forward-facing public duties, although officials have stressed they need to carefully review each potential engagement, with adaptations made where necessary to prioritise his recovery.

While palace officials have been forced to cancel a number of public engagements in light of the General Election, key national and ceremonial events such as Trooping are not affected.
