Prince George has walked nervously into school on his first day with his father by his side but without his mother, the Duchess of Cambridge.
Kate had hoped to join the Duke of Cambridge on the school run but is suffering from severe morning sickness and was too ill to attend, Kensington Palace said.
The four-year-old prince was helped out of the car by William after being driven through the gates of Thomas's Battersea, a fee-paying independent school in south London.
The prince would be known as George Cambridge to his classmates, the palace said.
