PRINCE HARRY TO PROPOSE TO HIS GIRL FRIEND SOON.

They predict an announcement by the end of the year and a wedding in the spring.

Harry, 28, has been talking about getting engaged and joking it could be "any day" now.

People working with him have witnessed him growing closer to society girl Cressida, with whom he has enjoyed an 18-month relationship.

Harry has been "going out of his way like never before" to woo Cressida, an insider said.

The couple have been together on safari in Botswana following his trip to Angola with anti-landmine charity The Halo Trust, which his mum Diana visited in 1997.

Security teams are now drawing up plans and duty rotas to prepare for the engagement, the insider added.

Cressida, 24, would then be given security cover, which would be factored in to the official rosters.

"The way it's looking now people close to Harry and Cressida predict an engagement by the end of the year and a spring wedding," said a Palace insider.

"Cressida is The One. He's so close to her. All the tell-tale signs are there.

"People have heard Harry talking about how special Cress is and about getting engaged.

"He says 'They are all waiting for me to propose any day', then he grins.

"It's his idea of a joke. He takes everything like this light-heartedly. But we know his true feelings."

The insider added: "He is taking a lot of time and trouble to devote so much time to her and see her as often as he can.
