LONDON — Prince William in an emotional Instagram post said that while the world has lost a leader, "I, however, have lost a grandmother". He was speaking two days after Queen Elizabeth II had died.

Prince William and his wife Catherine have been named the new Prince and Princess of Wales by King Charles III. "Today, I am proud to create him Prince of Wales, Tywysog Cymru," said the King, who previously held the title.

The King made the comments in his first address to the nation following the death of the Queen, aged 96. "With Catherine beside him, our new Prince and Princess of Wales will, I know, continue to inspire and lead our national conversations," he said.

The pair will also take the Duke and Duchess of Cornwall titles, previously held by the King and Camilla, the new Queen Consort.

Earlier, in a short statement posted to Instagram, Prince William said that while the world has lost a leader, "I, however, have lost a grandmother".

"I knew this day would come," he said referring to the Queen's passing, "but it will be some time before the reality of life without Grannie will truly feel real."

He added: "I will honor her memory by supporting my father, the King, in every , way I can."

Meanwhile, it was said that Queen Elizabeth II's funeral will be held on Monday Sept. 19 at Westminster Abbey in London, Buckingham Palace has confirmed. Princess Anne will accompany Queen Elizabeth II's body to London ahead of the funeral, Buckingham Palace added

Buckingham Palace said the coffin would depart for Edinburgh airport on Tuesday and then be flown to London by RAF Northolt, with the Queen's only daughter on board.

The coffin is expected to arrive at Buckingham Palace at 20:00 GMT on Tuesday, where King Charles III and Queen Camilla will witness its arrival. The Queen will lie in state for four days before her funeral on Sept. 19, Buckingham Palace has confirmed.

She will be taken from Buckingham Palace to Westminster Hall on Wednesday, where the coffin will be rested on a raised platform, known as a catafalque.

Her coffin will be draped in the Royal Standard flag and once in Westminster Hall it will be topped with the Imperial State Crown, orb and scepter. Members of the public will then be able to file past and pay their respects.

The grand hall is the oldest part of the Palace of Westminster, at the heart of the British government.

The last member of the Royal Family to lie in state in the hall was the Queen Mother in 2002, when more than 200,000 people queued to view her coffin. — BBC
