Princess Beatrice and Chief Scout Bear Grylls met 300 young achievers in the royal surroundings of Windsor Castle's Quadrangle on Sunday.

The 300 Queen's Scouts were all there to receive their Queen’s Scout Awards - the highest honour in scouting for personal achievement.

Mr Grylls is an international adventurer well known to millions of television viewers as well as being Chief Scout.

The Queen has regularly attended the ceremony over the years but this time her granddaughter Princess Beatrice of York provided the royal seal of approval, joining Mr Grylls in meeting and congratulating the young prizewinners.

They were aged between 16 and 25, came from all over the country and had completed a range of challenges, ranging from an expedition in wild country, to five-day residential project in unfamiliar environment or simply mastering a new skill.

Mr Grylls said: "During their time scouting all these young people have worked incredibly hard to learn new skills and achieve their Queen’s Scout Awards. I am so full of admiration for their spirit, grit and determination. They have served their community, lead others and undertaken expeditions in the UK and around the world. As Queen's Scouts they are leading lights and an inspiration to over half a million scouts in the UK and I am so pleased that scouting has honoured them today.”

The annual Windsor Castle event has been held regularly since 1934 on the Sunday nearest to St. George's Day.

Since the Queen’s Scout Award was instigated, over 100,000 have been presented to young men and women for outstanding personal achievements and service to their local communities. They have learnt new skills and taken part in many of the 200 different activities on offer by Scouting across the UK.
