Prince Harry's love: William speaks out

Prince William is deeply unhappy over his younger brother’s decision to issue an unprecedented public statement about his new girlfriend, Meghan Markle.

The future king is understood to be concerned that 'hot-headed' Prince Harry officially confirmed his relationship with the 35-year-old American actress by releasing an emotional tirade against the media and online commentators, sources said.

William, 34, and Harry, 32, are very close, living yards from each other at Kensington Palace and sharing both an office and a charitable foundation.

But despite his support for Harry, William is fiercely protective of his family’s privacy and believes his more open brother made a mistake in wearing his heart on his sleeve.

"He thinks Harry made a mistake in confirming the relationship and releasing such an emotional statement so soon [into it]," one well-placed Palace source told the Mail.

"He feels that the statement offered up too much information and only served to fuel speculation about how serious Harry is about Meghan. It could also put him in a difficult position in the future regardless of whether the relationship leads to something or not.

"William knows that his brother can be hot-headed and understands that it is something he felt very strongly about. Privately, he shares a lot of the sentiments he and Meghan expressed as, make no mistake, she was very involved in the statement too.

"But he believes it was wrong to make his feelings so public."
