Members of the Scout Association around the world have celebrated the centenary of the iconic movement this week with celebrations including huge jamborees and camping trips.

The celebrations were concentrated on Brownsea Island, Dorset, the site of the first-ever camp held by Robert Baden-Powell in 1907 for just 20 boys and now a National Trust property.

Around 300 scouts hailing from 160 countries have camped on Brownsea Island this week, while 40,000 scouts and leaders from across the globe met at Hylands Park near Chelmsford, Essex, for a vast World Scout Jamboree that was opened on Saturday by Prince William.

On Wednesday, scouts around the world, from Namibia to Sydney and Korea renewed their promises in s a series of Sunrise ceremonies, with chief scout Peter Duncan signalling the centenary by blowing the same African kudu horn that Lord Baden-Powell blew at the start of the very first Scout camp.

In a statement, the Scout Association said: "Scouting's Sunrise is the biggest and most significant expression of peace and unity the world has ever witnessed. It is the perfect opportunity to look to the past, present and, most importantly, the future of Scouting."

Founded exactly 100 years ago on Wednesday, the Scout Association was the brainchild of Lord Robert Baden-Powell of Gilwell, who published the famous Scouting for Boys in 1908, and the organisation now has an estimated 28 million members worldwide.
