London: Prince Harry has announced his engagement to actress Meghan Markle, with a royal wedding to take place in Britain early next year.
Prince Charles' official residence Clarence House announced the engagement at 10am on Monday, after a weekend of speculation in the British press that the announcement was imminent.
The couple became engaged earlier in London this month, Clarence House said, and both families had given their blessing to the union.
Prince Harry and Markle have been in a relationship since 2016, after first meeting in July of that year. The wedding planned for sometime between March and May next year, will fall close to the birth of Prince Harry's brother Prince William's third child with his wife Kate.
Markle, a divorcee, is the American daughter of a Caucasian father and African-American mother and, soon after their relationship was announced, Prince Harry's communications secretary issued a stern statement warning the intrusion into the actress' life had "crossed the line". The statement also hit out at "racial undertones" in comment pieces.
