Jubilee - live: Platinum Party at the Palace begins with surprise sketch of the Queen and Paddington

As the Queen lit the principal beacon at Windsor Castle, an expected 2,000 beacons were lit concurrently around the globe.

Here is the one in Islamabad, capital of Pakistan:

The principal beacon lit by the Queen at Windsor sparked thousands around the globe, none more spectacular than the Tree of Trees outside Buckingham Palace in London.

Prince William was at the lighting ceremony to represent the royal family.

Commentators are saying the tree emphasises the royal family’s environmental bent.

An image of the Queen was projected onto Buckingham Palace ahead of the beacon lighting ceremony as crowds looked on from The Mall.

Joe and Jill Biden have offered their congratulations to the Queen on her platinum jubilee.

The US president said she had inspired people with her “selfless devotion and service” to the UK and the Commonwealth for 70 years.

“Throughout your reign, the relationship between the United Kingdom and the United States has grown stronger and closer than ever,” he said.

Mrs Biden said the joy the monarch had brought the American people through her visits to the US, together with the solidarity she had shown in times of tragedy, had “deepened the friendship and profound connection between our countries”.

“Joe and I were so touched by the generosity and welcome you showed to us when we visited you at Windsor Castle last year, during our first visit overseas as president and first lady,” she said.

Beacons were lit in towns and cities across Northern Ireland after the Queen sparked the principal beacon at Windsor.

Sites included Titanic Belfast and St Columb’s Cathedral in Londonderry.

Further beacons were lit nearby at Castle Island, Topped Mountain and the Enniskillen Royal Grammar School.

A Zambian woman who was trafficked by her own father has spoken of the “surreal” experience of lighting the UK’s first Platinum Jubilee beacon.

Alina Karimamusama, who works with the Queen‘s Commonwealth Trust, ignited the large brazier at Coutts bank in central London.

Known as the Queen‘s Bank because it has served every monarch since George IV, it hosted a party for the event with guests including broadcaster Andrew Marr.

More than 2,000 beacons will be lit across the UK and the Commonwealth, in what Ms Karimamusama said was a mark of “hope”.

“It represents the possibilities that young people from communities like mine, young people like me, can reach when they are given the right support,” she said.

Beacons are traditionally lit for royal occasions, having previously been used to mark the silver, golden and diamond jubilees of the Queen, along with Queen Victoria’s Diamond Jubilee in 1897.

Key workers, charity volunteers and members of the armed forces have been invited to the Queen’s service of thanksgiving in recognition of their contribution to public life.

More than 400 people, who have been making a difference either nationally or locally, are among the guests and many have been working tirelessly during the pandemic.

They will join members of the royal family at St Paul’s Cathedral to celebrate the monarch’s 70-year reign, although the Queen herself will not attend after experiencing “some discomfort” following previous mobility issues.

Senior members of the monarchy attending include the Prince of Wales, Duchess of Cornwall, the Duke and Duchess of Cambridge and the Duke and Duchess of Sussex, who will be joined by the extended royal family.

Charles will officially represent the Queen at the service.

Those invited in recognition of their service have all been recipients of honours in the New Year or Birthday Honours lists and their number also includes public servants and representatives from social enterprises and voluntary groups.

She is loved and respected thanks to her dedication to duty, but despite his best efforts, the Prince of Wales still does not command the kind of popularity that his mother has enjoyed. Emma Mackenzie looks at the Queen’s unique popularity:
