Britain's Catherine, Princess of Wales (L) and Britain's Prince William, Prince of Wales (R) walk with their 13-year-old son, Britain's Prince George of Wales (C), as he arrives for his first day at Eton College, in Eton, west of London.

Britain's Prince George started at the prestigious private school Eton College on Tuesday, arriving for his first day with parents Prince William and Catherine, Princess of Wales.

Under a steady drizzle, the 13-year-old prince was welcomed to the world-famous school by its headmaster Simon Henderson who told the future king: "Welcome, good luck, enjoy it."

George - who is second in line to the throne, after his father - will complete his secondary education at the school, which charges more than £63,000 ($85,000) in annual fees.

According to UK media, the young prince will board at the elite institution, despite it being just a few kilometres away from the family home in Windsor, west of London.
