Royals at Camilla's son's wedding

About 180 guests braved the rain for the Oxfordshire ceremony

Tom Parker Bowles, son of the Duchess of Cornwall and stepson to Prince Charles, has married magazine fashion editor Sara Buys.

Among the guests who braved the rain for the ceremony in Rotherfield Greys near Henley-on-Thames, Oxfordshire, were Princes William and Harry.

They were joined by the Royal couple, as well as ex-chancellor Lord Howe and Annabel Elliot, the Duchess's sister.

The bride, who was 15 minutes late, wore an Alexander McQueen dress.

The service lasted about 45 minutes and guests sang the hymns Jerusalem, Glory, Glory Hallelujah and I Vow To Thee My Country.

Both sets of parents, Caroline and William Buys and the Duchess of Cornwall and Andrew Parker Bowles, witnessed the signing of the register together with the Prince of Wales.

The Reverend Brendan Bailey said: "It is always an incredible privilege to marry anyone, and the fact that the Prince of Wales, the Duchess of Cornwall and the two young princes were here was an added bonus."

About 450 guests attended the reception at the bride's home near Henley.

The princes' attendance was an 'added bonus'

Ahead of the wedding, Ms Buys - a fashion features editor for Harpers and Queen - had said the wedding would be "so humungous that it makes even Liza Minnelli and David Gest's global guest-listed nuptials seem like an intimate dinner".

Eton-educated Mr Parker Bowles, the son of Camilla and her first husband Andrew, made headlines in 1999 when he was exposed for taking cocaine.

The Prince of Wales was reported to have telephoned the then 24-year-old, who is a food writer, and given him a severe scolding.
