Britain's Prince Harry expressed "great sadness" over his decision to step down from royal duties.
"Our hope was to continue serving the queen, the Commonwealth and my military associations without public funding. Unfortunately, that wasn't possible," Harry said in his first public statement.
"I've accepted this knowing it doesn't change who I am, or how committed I am. But I hope that helps you understand what it had come to, that I would step back from all I have ever known to take a step forward into what I hope can be a more peaceful life.
"The decision that I have made for my wife and I to step back is not one I made lightly," he said. "It was so many months of talks after so many years of challenges. And I know I haven't always gotten it right, but as far as this goes, there really was no other option."
In a speech to the Sentebale charity on Sunday, a clearly upset Harry said it has brought him "great sadness" and that there was "really no other option".
"The UK is my home and a place that I love. That will never change," he said.

Foreign ministers from the Gulf Cooperation Council (GCC) and the European Union have strongly condemned the Iranian attacks targeting GCC states, calling them a direct threat to regional and global security.
US President Donald Trump claimed the right to join Iran in deciding its next leader as the war escalated, with US and Israeli jets hitting areas across the country and Gulf cities coming under renewed attack.
British Prime Minister Keir Starmer said on Thursday that four additional Typhoon fighter jets would be sent to Qatar amid the ongoing regional developments, insisting that the UK has the right plan for defence.
