The pair, who had been dating for two years, ended their relationship amicably.

“It’s very, very sad that they have decided to split. It’s very amicable but they have decided to go their separate ways,” the source said.

One of the reasons the couple decided to call time on their relationship is thought to be to allow Cressida, who is just 25, to concentrate on her career.

Cressida had been widely tipped to marry Harry, with speculation growing in March after she joined the Prince at one of his official engagements for the first time.
