Queen Elizabeth pulls out of Jubilee thanksgiving service

Britain celebrates the second day of Queen Elizabeth's Platinum Jubilee on Friday, with the highlight a service of thanksgiving attended by senior royals and politicians that the 96-year-old monarch herself will miss due to ongoing mobility issues.

The four days of events kicked off on Thursday, when a happy-looking Elizabeth waved to crowds from the balcony of Buckingham Palace after a military parade and Royal Air Force fly-past, and later led the lighting of the Principal Platinum Jubilee Beacon at her Windsor Castle home.

The celebrations continue with a National Service of Thanksgiving at London's St Paul's Cathedral to pay tribute to the sovereign's 70 years on the throne but the queen will be absent, pulling out late on Thursday, slightly taking the sheen off the day's party atmosphere.

"The queen greatly enjoyed today's Birthday Parade and Fly-past but did experience some discomfort," Buckingham Palace said in a statement.

Officials said the journey from Windsor Castle, where she spends most of her time, to London and the activity involved for the service was too much and a regrettable but sensible decision had been taken.

A palace source said it had always been the queen's hope that she would attend rather than a firm commitment.

She will not be the only absentee. Her second son, Prince Andrew, 62, has tested positive for COVID-19 and will also miss the service, a Buckingham Palace spokesman said on Thursday.

That will potentially spare the royals some awkwardness, with Andrew's reputation shattered after he settled a U.S. lawsuit in February in which he had been accused of abusing an underage woman, claims he denied.

However, it is expected grandson Prince Harry and his wife Meghan, who have made almost no public appearances in Britain since stepping down from royal duties two years ago, will be there.

The couple moved to the United States to lead a more independent life, and have since delivered some stinging attacks on Buckingham Palace and the royal family.

The service will include Bible readings, prayers, and hymns to express gratitude for Elizabeth's reign. Political figures from Britain and across the world will be in attendance, and UK Prime Minister Boris Johnson will give a reading.

Thursday marked not only the start of the Jubilee, but also the 69th anniversary of the coronation of Elizabeth, who became queen on the death of her father George VI in February 1952.

She has now been on the throne for longer than any of her predecessors in 1,000 years, and is the third-longest reigning monarch ever of a sovereign state. Opinion polls show she remains hugely popular and respected among British people.
