The sixth anniversary of Prince George is marked by new photos

Prince George is seen smiling in a football jersey in England for the official photographs released on the occasion of his sixth birthday.

Kensington Palace has published three recent photos taken by his mother, the Duchess of Cambridge.

The third on the throne will be six on Monday.

Two of the images show the prince dressed in an English white shirt and smiling in the garden of his home at Kensington Palace.

A third shows him on family vacations, wearing a green polo shirt and a blue and white striped shorts.

Prince George Alexander Louis of Cambridge was born in London in the Lindo Wing private wing of St Mary's Hospital.

He appeared in front of the world media a day later, when Prince William and Catherine stood against him on the hospital steps.

This year, he appeared on the balcony of Buckingham Palace and in his mother's garden, the Chelsea Flower Show.

Earlier this month, the young prince received a tennis lesson from Roger Federer at Kate's parents' home in Bucklebury, Berkshire.

The sports star said that George was "cute" and had a "good" technique.

The great-grandson of the queen, George is expected to take the throne after his grandfather and his father.

The prince finished his first year at Thomas Battersea's private school.

He will begin his second year in September, his last year at the lower school before going to college.
