Two teenagers have achieved the rare feat of a full house of 45 Guiding badges - and say sibling rivalry helped them on their way.
From camping and chocolate studies to language interpretation and party planning, twins Abby and Bethany Williams, 15, from Gravesend in Kent have mastered it all.
Visiting Guide headquarters in Buckingham Palace Road, central London, they said they hope the skills they have learned will help them in later life.
Bethany said: "When I leave school I want to become a paramedic, so I know Guiding has taught me skills I'll need, like meeting and talking to new people.
"I'm glad my sister has been involved as well but I know I would have done all the same things if she wasn't. We have been a bit competitive because when we started she was ahead in the number of badges she had, but then after a while I had caught up and then overtook her."
The pair have been involved in Guiding since the age of five when they joined their local Rainbow group, and have been members of the 1st Gravesend Guides since they were 10.
Among their badges, gained over three years, are the prestigious Commonwealth Award and the Baden-Powell Award - the highest accolade available to Guides.
Both said the camping and holiday badges were the most fun, while interpretation was the most difficult skill to master.
Abby said: "I love getting involved in all the activities I can, such as things like crate-stacking and abseiling. I also really enjoyed completing my Baden-Powell Award. Probably the most fun was building bivouacs and sleeping in them while we were away on camp."
