The children were handed flowers behind the door when one of the little bridesmaids began to cry.

The Cambridges' nanny, Maria, lifted her up to comfort her, as Prince George looked up at the tearful girl.

A member of Prince Harry's household bent down to help to adjust one of the bridesmaid's dresses.

When Meghan appeared through the doors of the chapel, sunlight streaming in behind her, she turned to smile and wave at the children who were standing to her right behind the door.

Ms Markle arrived to marry Prince Harry in a simple but beautiful pure white dress and extraordinary long trail leaving the groom close to tears.

Harry grabbed his bride's hand and told her: 'You look amazing' and said 'thank you, pa' after his father Prince Charles walked her down the aisle of St George's Chapel, Windsor.

Ms Markle's wedding dress has been designed by the acclaimed British designer, Clare Keller, the first female Artistic Director at the historic French fashion house Givenchy.

The veil was held in place by Queen Mary's diamond bandeau tiara, lent to her by The Queen, made in 1932 - an outfit that left her mother Doria Ragland, 62, in tears.

Prince Harry looked nervous as he arrived at St George's with his best man William but quickly warmed up waving and grinning at crowds before greeting guests inside and outside the chapel.
