Princess Diana's hopes for a closer relationship between Prince William and Prince Harry have been revealed in a previously unseen letter.
Written less than two years before her death, it shows the late Princess of Wales – who died aged 36 in a Paris car crash in 1997 – expressing her desire to teach her sons "the importance of communication on a deeper level".
The handwritten correspondence, dated November 1995, was sent by Diana to royal supporter Michael Barratt after he wrote to her following her landmark BBC Panorama interview.
