Queen Camilla leaves party at Oswald’s to celebrate her nephew Ben Elliot’s investiture

Queen Camilla took time out of her busy schedule to support her nephew Ben Elliot as he was officially inaugurated as Knight Bachelor on Thursday.

Sir Ben, 48, a former Conservative Party chairman and son of Camilla’s sister Annabel Elliot and her late husband Simon, was knighted in Boris Johnson’s resignation honors.

Celebrating after the ceremony, Camilla headed to Mayfair’s private members’ club, Oswald’s, alongside a group of well-heeled guests.

The Queen, who looked typically glamorous in a dark blue dress with heeled boots and a black jacket, was joined by makeup mogul Charlotte Tilbury, former MP Zac Goldsmith as well as her children Laura Lopes and Tom Parker-Bowles.

The monarch has had a busy few weeks with trips to Kenya and France before returning to the UK for the official opening of Parliament and attending memorial services.

Sir Ben, 48, a former Conservative Party chairman and son of Camilla’s sister Annabel Elliot and her late husband Simon, was knighted in Boris Johnson’s resignation honors.

Annabel, Camilla’s little sister, has been regularly at her side since the eldest became queen. So it’s no wonder she attended the event to support her nephew.

Typically glamorous in appearance, makeup mogul Chalrotte Tilbury, 50, showed off her scarlet red hair in all black.

A fur collar joins the fitted jumpsuit and blazer, which she accessorizes with a gold chain.

Meanwhile, Lord Zac Goldsmith joined the celebrations.

Zac, a former MP and London mayoral candidate, is the son of James and Annabel Goldsmith – whose family has been close to the royal family for years. Her sister Jemima was a close friend of Princess Diana.

Camilla’s son Tom, a food writer, opted for a suit and navy jumper for the occasion.

In addition to working in politics, Ben has made money through his concierge company Quintessentially.

According to Tatler, the company provides “sinister” services to “billionaire members”, including tea bags sent to Madonna in America, lunch on an iceberg and closing Sydney’s Harbor Bridge for a marriage proposal.

Makeup mogul Charlotte Tilbury joined the Queen, who looked typically glamorous in a dark blue dress with heeled boots and a black jacket.

According to the Society Bible, Ben has extremely close connections – as a long-time friend of the Goldsmiths and “wingman” to cousin Tom – who was there when William had his first drink.

Before marrying his very glamorous wife Mary-Clare (daughter of rockstar Steve Winwood), he dated many beauties including Jade Jagger, Sophie Dahl and Cat Deeley.

“He can be found at 5 Hertford Street, in the drawing rooms of Highgrove or at a Boxing Day lunch with the Beckhams.

“Such is his overt and visible glamour, election campaigners who went door-to-door with him on Putney housing estates telephoned central office to express their concern that he was being attacked,” claims Tatler.

Camilla’s appearance comes after a busy week for the royal.

Yesterday she paid tribute to fallen soldiers in a poignant ceremony at the Field of Remembrance at Westminster Abbey.

Camilla, 76, opted for dark green and black tones as she bowed her head in respect ahead of Armistice Day on Saturday.

Following prayers led by the Dean of Westminster, the Right Reverend Dr David Hoyle and the Right Reverend Anthony Ball, Rector of St Margaret’s Church, the Queen placed a small wooden cross adorned with a red poppy within a larger cross made of flowers forever associated with the First World War.

After laying down the cross, Camilla and hundreds of veterans fell silent at 11 a.m. as the chimes of Big Ben rang out.

Her Majesty paid tribute and recognized the sacrifices of those who fought and died for their country during her first visit to the Abbey since the Coronation.

The previous week, she inaugurated Parliament alongside her husband, King Charles, and visited Koreatown.
