The Queen has lost a second loyal aide following the death of Lady Farnham just weeks after the passing of devoted friend and former Mistress of the Robes, the Duchess of Grafton. 

Diana Maxwell, Lady Farnham, who had been the Queen's Lady of Bedchamber since 1987 and rode with the Queen on the way to her Diamond Jubilee service in 2012, died four days after Christmas aged 90. 

She also joined the Queen on royal tours during her 44 years of service, including the highly successful tour of the Republic of Ireland in 2011 due to her Irish connections. 

It follows the death of Ann Fortune FitzRoy, the Duchess of Grafton, aged 101 last month and is another blow after the passing of husband Prince Philip in April. 

Lady Farnham was married to Barry Maxwell, the 12th Baron Farnham - a top City banker and Irish peer who died in 2001.

A royal source told The Telegraph: 'It is very sad for the Queen. Everyone loved Lady Farnham, she was always so good humoured. She was also a very glamorous and attractive woman.

'She was always very generous to new people joining the household. 

'It has not been a good year for the Queen - losing her husband and then the Duchess of Grafton and now Lady Farnham.

'They were dear friends who supported the Queen on official duties. Unfortunately a sad consequence of living a long life is that you have to say goodbye to a lot of people you care about.'

Lady Farnham was a close friend and supported the Queen for decades, most notably sitting alongside the monarch during Diamond Jubilee celebrations in 2012 when Prince Philip was unable to attend.

Born Diana Marion Gunnis, she married Lord Farnham in 1959.

The couple adopted two daughters, Harriet, 57, and Sophia, 54, and had four grandchildren - Araminta, 28, Henry, 26, Elsa, 15 and Celia, 13.

Lady Farnham joined the Royal Household in 1987, more than 30 years after Duchess of Grafton, but she was appointed Commander, Royal Victorian Order (CVO) in 1998 after the Queen recognised her personal service.

She was then appointed Dame Commander, Royal Victorian Order, an award made personally by the Queen for services to the sovereign, in 2010.  

Her death follows a turbulent year for the Queen in which she had to deal with the departure of grandson Prince Harry and Meghan Markle to the US and the passing of her husband.

Prince Philip was her 'strength and guide' throughout their 73-year marriage and her 69-year reign.

Crowds of mourners laying flowers and tributes at palaces became so large in April last year that they were told to disperse because of the pandemic following his death. 

The nation was subsequently left heartbroken by photographs of the grief-stricken Queen sitting alone during her husband's funeral as she was forced to mourn away from her devastated children and grandchildren during the Covid-secure ceremony. 

The Queen proudly displayed a photo of her 'beloved' Prince Philip and donned a sapphire brooch she wore on her honeymoon in 1947 and again for her diamond wedding anniversary during her Christmas Day speech last week.

Facing her first festive season without her husband of 73 years, Her Majesty, 95, presented a 'particularly personal' address to the nation - paying tribute to the Duke of Edinburgh and saying his ‘mischievous, enquiring twinkle was as bright at the end as when I first set eyes on him’.

The monarch described there being ‘one familiar laugh missing’ this Christmas as she made her most fulsome public tribute to the nation’s longest-serving consort since his death in April aged 99.

The speech also came just weeks after the passing of close friend the Duchess of Grafton.

The Duchess was appointed the prestigious Dame Grand Cross of the Royal Victorian Order in 1980 and their close relationship was underlined when she made the monarch the godmother to her second daughter in 1954.

She was also only one of two Mistress of the Robes during the Queen's reign - formerly a role wielding responsibility for the monarch's clothes and jewellery. 

She first joined the Royal Household in 1953, the year of Queen Elizabeth's Coronation, as Lady of the Bedchamber for the Queen, before becoming Commander of the Royal Victorian Order in the New Year's Honours list 1965.
