Prince William turns 'furious' as Harry's secret palace ties emerge

Prince William is reportedly "worried" as he believes Prince Harry still has "friends" inside the palace.

On Tuesday, an insider spilled to RadarOnline.com that the Prince of Wales fears his estranged brother still has spies inside the palace feeding him information.

"William's concern isn't that there is some organized spying operation. It's that Harry spent his entire life inside this institution and naturally still knows people throughout the royal world," the insider claimed.

The royal expert further said, "William worries that conversations can travel and that details he regards as private might eventually be finding their way to his brother now that he is back in Britain."

"He's therefore become extremely guarded about who is told what. The difficulty is that many people have worked with both brothers or remain personally fond of Harry, so William knows he can't simply draw a line through the Palace and decide everyone belongs on one side or the other," a tipster continued.

"That's created an atmosphere where he's increasingly cautious about information concerning his family," the source added.

For those unaware, Prince Harry and Meghan Markle moved back to England last month, accompanied by Prince Archie, 7, and Princess Lilibet, 5.
