The event, titled "Women in Music," will be hosted by Alicia Kennedy, the Baroness Kennedy of Cradley, former deputy general secretary of the Labour Party and now life peer on the Labour benches and a human rights activist.
The event will be attended by parliament members, businesspeople, members of the music industry and representatives of the British association for women's rights.
"This is a surprising invitation, which made me very happy," says Rita. "In the past few years I have taken upon myself the mission of trying to advance the empowerment of women through music, and in general. The invitation from the UK House of Lords strengthens the notion that this is one of the most important things I have ever done."
As opposed to her performance in the UN, this time Rita has not been asked to sing.
"I wrote a 15-minute speech and asked to leave the rest for questions from the audience," she says. "In total I'll be on stage for about an hour, and I'm very excited about it. I don't know if one can sing there, at the House of Lords, but I might do it spontaneously."
