The Queen's was 'hurt' by some of Prince Harry and Meghan Markle's plans for their wedding at Windsor Castle and declared exasperatedly: 'But it's my house - and I’m paying for it', a close friend of the monarch's cousin has claimed.

Her Majesty is said to have disapproved of their guestlist and the couple's preference to invite 'random' celebrities over family members in May 2018.

‘That was just yet another irritation for the Queen’, seasoned royal expert Sally Bedell Smith, a celebrated biographer who was popular in royal circles, said today.

Elizabeth II was also apparently 'really annoyed' the Sussexes went directly to the Archbishop of Canterbury to ask him to marry them at St George's Chapel - even though she was Defender of the Faith and Supreme Governor of the Church of England.

Harry's grandmother was more excited about Princess Eugenie's wedding in October that year only for the Duchess of Sussex to announce she was pregnant on the day, it was also claimed today.
