Prince William performed his duties as an usher at the Duke of Westminster’s marriage to Olivia Henson today.
The Prince of Wales was pictured waving to the cameras as he arrived for the service at Chester Cathedral.
But his brother Harry, also one Hugh Grosvenor’s closest friends, was not in attendance, choosing to remain in California instead.
An insider this week said it would have been ‘difficult’ for Harry to attend, and the decision for him not to come was a ‘understanding between the two friends’.
The Duke of Westminster is the godfather to William’s son Prince George and Harry’s son Archie.

Sources close to Prince Harry briefed People Magazine in America and said he had spoken to the Duke of Westminster, and discussed tensions within the Royal family.
People Magazine reported it can confirm Harry was invited to the wedding and was not excluded from the event.
Their report reads: ‘However, there was an acknowledgment on both sides that it would be difficult for Harry to attend.’
While a source added: ‘It was an understanding between the two friends.’
An insider close to the newly married couple added: ‘The decision certainly avoided the inevitable clamour had estranged brothers Prince William, 41, and Prince Harry both attended the nuptials, eliminating the possibility of the big day being overshadowed for the couple.’
The publication added that: ‘The Duke of Sussex sends ‘his love and support and admiration for the couple’ for their wedding day.’
Princes Harry has agreed to stay away after the publishing of his memoir Spare made damning allegations about the Royal Family.
Up to 400 guests attended the wedding which has been highly anticipated for months amongst society circles.
Olivia, 31, looked stunning in her dress and blue shoes as she arrived at the 11th Century Cathedral just before midday.
The bespoke embroidery design on her gown and veil was hand drawn by Emma Victoria Payne, featuring floral motifs and edgings from Olivia’s great great grandmother’s veil from around 1880.
The bride is wearing the Faberge Myrtle Leaf Tiara made for Grosvenor brides to wear on their wedding day.
It has been in the Grosvenor family since its creation in 1906. Olivia’s bouquet was made of flowers picked from the gardens of the duke’s family home, Eaton Hall.

Princess Eugenie is among the many guests to have arrived at the event, while the Princess of Wales- who has been out the spotlight as she undergoes preventative chemotherapy – was not expected to attend.
Shortly before 11am, coachloads and minibuses of excited guests began arriving and filing into the side door of the Cathedral.
As they rounded the corner, many smiled and waved back to the crowds lining the streets, who were cheering their arrival.
William, dressed like others in morning suit, smiled as he exited a black minibus to head towards the building.
Guests joined the long queue snaking into the Cathedral, waiting to be shown to their seats by Prince William and the other ushers.

This week a floral arch was constructed around the huge West Door of the 1,000-year-old Cathedral in the heart of the city.
A staggering 100,000 flowers have been planted throughout the city – all paid for by the Duke – which will be donated to charity following the ceremony.
