Camilla stuns in Anna Valentine as she arrives at the Royal Wedding

He has stepped in to walk Meghan up the aisle after a last-minute dropout from Thomas Markle.

And the Prince of Wales was all smiles as he arrived at St. George's Chapel, Windsor Castle this morning with the Duchess of Cornwall.

Dapper in a grey morning suit, Charles, 69, arrived in a private car with Camilla, who looked resplendent in a blush pink Anna Valentine ensemble.

She teamed the pink silk marocain asymmetrical coat dress with an elaborate, ice pink feathered Philip Treacy hat.

Kensington Palace announced this week that Charles was 'pleased' to have been asked to walk his future daughter-in-law down the aisle after Thomas Markle Snr dropped out at the last minute, citing health problems. 

Charles met the bride halfway into the chapel this morning, as Meghan had always planned to walk in by herself.

The American-born former actress asked the Prince of Wales after discussions with Harry. 

Charles released a statement earlier this week saying he was 'pleased to welcome her to the Royal Family in this way'.

Meghan's mother Doria Ragland had been expected to step in for Thomas Markle, whose deal with a paparazzi photographer threatened to overshadow the biggest and happiest day of his daughter's life. 

Charles and Camilla were among the last to arrive this morning, minutes after Prince Andrew, Princesses Beatrice and Eugenie, and Princess Anne arrived.

The Queen and the Duke of Edinburgh arrived in a chauffeured vehicle, entering the chapel through the Gailee Porch.  

Glamorous non-royal guests included Victoria and David Beckham, George and Amal Clooney, and Serena Williams. 

After leaving Clivedon House Hotel this morning, Meghan was driven from Windsor Castle to the chapel and entered at the famous West Door followed by her six bridesmaids and four page boys just before midday .

The bride walked through the Nave where Prince Charles wase waiting at the start of the Quire - half way down the chapel - to take her to the altar.
