The controversial change, one of the biggest in the organisation’s 103-year-history, was taken in an attempt to show the movement welcomed “all girls, of all faiths and none”.

However, the Guides decided to retain the pledge to serve their patron Queen Elizabeth II in the Promise. Anti-monarchy campaigners told The Independent that the organisation had “missed” an “opportunity” to truly open up the organisation.

From September, all new members over the age of seven who make the Girl Guide  Promise will pledge an oath to “be true to myself and develop my beliefs” and “to serve my Queen and my community.”

Girlguiding boasts more than half a million members, but it is the first time the promise has been changed since 1994. While the promise is optional, girls will not be able to secure the highest Guide badges without taking it.
