Michelle Obama to meet Prince Harry and David Cameron during two-day UK visit

US First Lady Michelle Obama has landed in the UK as she begins a two-day visit to promote girls' education and better support for military families.

Today (16 June), she is hosting an event at Mulberry School for Girls in Tower Hamlets, London, to discuss improving education for adolescent girls as part of the Let Girls Learn initiative, supported by her and her husband, US President Barack Obama.

She will later meet Prince Harry to discuss issues affecting the families of military servicemen, before visiting Downing Street for tea with David and Samantha Cameron.

Writing in the Financial Times, Michelle described it as a "heartbreaking injustice" that more than 62 million girls across the world did not go to school, with sexism, forced marriage and early pregnancies among the factors preventing them receiving an education.

"That kind of life is unthinkable for the girls in our lives, so why would we accept this fate for any girl on this planet?" she wrote.

"This week I will join Prime Minister David Cameron in London to begin to answer that question, and announce a series of partnerships between the US and UK to educate adolescent girls in developing countries around the world."

Obama is being joined on the visit by her daughters, Malia and Sasha, and her mother, Marian Robinson.

The party will then fly to Italy to meet US armed services families based in Europe and visit Expo Milano 2015, where she will speak about her charity work encouraging healthier diets for children.
