American Marconi Wireless News - Charles III to be crowned king in first UK coronation since 1953

St Edward's Crown -- a solid gold, sacred symbol of the monarch's authority used only once in their reign -- will be placed on Charles's head at 1100 GMT to cries of "God Save the King".

Trumpet fanfares will sound through London's Westminster Abbey and ceremonial gun salutes will blast out across land and sea to mark the first coronation of a British monarch since 1953 -- and only the fifth since 1838.

Bells will peal in celebration at churches across the land, before liveried soldiers on foot and horseback stage a 7,000-strong military parade stretching through the streets of the capital.

King Charles and his wife Camilla, who will be crowned queen, will return to Buckingham Palace in the rarely used horse-drawn Gold State Coach past huge crowds, before watching a ceremonial fly-past from the balcony.

The coronation -- the first of a king since 1937, only the second to be televised and the first in colour and streamed online -- is the religious confirmation of Charles's accession.

Charles, 74, has been king since the death of his mother Queen Elizabeth II in September last year after seven decades as her heir apparent.

Much of the two-hour Anglican service, led by the Archbishop of Canterbury Justin Welby, would be recognisable to the 39 other monarchs crowned at Westminster Abbey since 1066.

But while many of the intricate rituals and ceremony to recognise Charles as his people's "undoubted king" remain, the king has sought to bring other aspects of the service up to date.

There are women bishops for the first time, while leaders of Britain's non-Christian faiths and its Celtic languages will play a prominent role.

As king, Charles is supreme governor of the Church of England but heads a more religiously and ethnically diverse country than the one his mother inherited in the shadow of World War II.

He has also sought to make the 2,300-strong congregation more reflective of British society, inviting ordinary members of the public to sit alongside heads of state and global royalty.

In another change, the coronation themes mirror his lifelong interest in biodiversity and sustainability.

Seasonal flowers and foliage from the wind-battered Isle of Skye in northwest Scotland to Cornwall at the tip of England's southwest coast, will fill the abbey.

Single-use plastic and floral foam have been banned and all the flowers will be donated to charities helping the elderly and vulnerable.

Ceremonial vestments from previous coronations will be reused, and the anointing oil will be vegan.

- Opposition -

Britain's Prime Minister Rishi Sunak described the coronation as "a proud expression of our history, culture and traditions".

The "moment of extraordinary national pride", he said, was "a vivid demonstration of the modern character of our country and a cherished ritual through which a new era is born".

But not everyone is convinced: polling indicates waning support for the monarchy, particularly among younger people, with calls for it to be modernised or even scrapped altogether.

Republicans who want an elected head of state have promised to protest, holding up placards stating "Not my king".

Overseas, Charles's time as the hereditary monarch and head of state of 14 Commonwealth countries looks increasingly fragile.

Jamaica and Belize have both this week signalled that they are moving towards becoming republics, while Australia, Canada and others may eventually follow suit.

Britons struggling with the soaring cost of living have meanwhile questioned why taxpayers should stump up for the coronation, with the bill estimated to be over £100 million ($126 million).

- Support -

Yet the huge crowds of royal fans that have been building all week on The Mall outside Buckingham Palace indicate that the royals still have a central role in British culture and history.

Many of those camping out to watch have flown in from abroad, underlining the royal family's untouched position as Britain's leading global brand.

The coronation is the centrepiece of three days of events, including a concert at Windsor Castle west of London on Sunday evening.

"It's so exciting," said charity worker Karen Chamberlain, 57, who has camped out for a prime spot with her sister and young son.

"None of us have ever lived a coronation. Our mother came to London in 1953. Being here is a way to say we are proud of the monarchy," she told AFP.
