Plans for the Queen Consort to be crowned using regalia containing the controversial Koh-i-Noor diamond may be axed because of ‘political sensitivities’, it has been reported.

When the King first raised the issue of his wife taking her place by his side at his coronation several years ago it was provisionally agreed that she would be proclaimed Queen Consort using the late Queen Mother’s crown, according to Mail+. 

The priceless piece features 2,800 diamonds with the front cross holding the famous 105-carat Koh-i-Noor diamond, one of the largest cut diamonds in the world.

But the Mail has learnt that there is ‘significant nervousness’ about this now given continuing controversy over ownership of the diamond, which originated in India and is claimed not only by the republic but also several other countries in the region.

When the King (pictured here with Camilla during the State Opening of Parliament in 2015) first raised the issue of his wife taking her place by his side at his coronation several years ago it was provisionally agreed that she would be proclaimed Queen Consort using the late Queen Mother’s crown, according to Mail+ 

The gem, which is held in a detachable platinum mount, may now be taken out of the crown before use – or the crown not even used at all in favour of something simpler, such as Queen Victoria’s coronet.

A source said: ‘The original plan was for the Queen Consort to be crowned with the late Queen Mother’s crown when her husband acceded to the throne.

That was certainly the agreement a few years ago when the whole idea of the Duchess of Cornwall becoming Queen Consort was first mooted

‘But times have changed and His Majesty The King is acutely sensitive to these issues, as are his advisors. There are serious political sensitivities and significant nervousness around them, particularly regarding India.’

Buckingham Palace declined to comment today.
