To mark the jubilee, over 2,500 public events are happening in the UK this weekend. In Bangladesh, the memorable occasion was marked at the queen's birthday party, hosted on May 25 under the theme "empowering girls to change their world," where a significant portion of the sponsorship raised for the event was used to support girls' education across Bangladesh through the British Council's EDGE Programme. British High Commissioner to Bangladesh Robert Chatterton Dickson said the queen has been a dedicated servant of the UK, the Realms and the Commonwealth and it is wonderful that "we can celebrate her service by lighting up our buildings on her birthday." "With over 260 official visits overseas, including to Bangladesh in 1983, the queen has been the UK's foremost diplomat, affirming old relationships and building new connections, strengthening the bonds of friendship, understanding and respect between the UK, the Commonwealth, and the rest of the world," the envoy said.
