"Unfortunately The Duchess of Cambridge remains unwell, and will not be able to accompany Prince George on his first day of school".
Despite Kensington Palace announcing last week that the Prince would be accompanied by both his mother and father for his first day, the Duchess of Cambridge was forced to pull out of attending last minute due to chronic morning sickness.
Royal fans across the country will be cooing over photos of Prince George as he begins his first day at primary school.
The youngster shook hands with Helen Haslem, head of the lower school, as the Duke held a school bag packed ready for his first day.
"TRH were met by the Head of Lower School, before The Duke took Prince George inside to his reception classroom", the palace explained in another Twitterpost.
As expected, he wore a school uniform: navy blue shorts, a navy blue sweater with red stitching, and a light-blue collared shirt underneath. Yes, Prince George has started his schooling as he was walked into the prep school holding his father's hand.
Thomas said that the school's hope was that "he will be himself".
George is the eldest child of the royal couple.
Ben Thomas, principal of Thomas's London Day Schools, said he would not be given "any special treatment at all".
"So we are not going to try to mould him into any kind of particular person and we wouldn't do that with any of our pupils". And fortunately for Kate, there will be plenty more school runs to do - and, of course, plenty more first days of school. George's class will have 20 students, and will be taught ballet, French, art, drama, and music-apart from regular school subjects.
