Harry’s emotional avalanche hits the Royal Family

This BBC interview with Prince Harry will become one of those famous moments when television collides with the world of the royals.

It was like an emotional avalanche. It began with some stones being kicked over with questions about security and then the interview turned into a spectacular release of what seemed to be a rolling mountain of pent-up frustration and a poignant sense of separation.

The starting point was Prince Harry’s defeat in the courts as he sought to overturn a downgrading of his security in the UK. He seemed wounded. Had he decided it was time to have his say? And then really say some more?

A conversation about security was suddenly becoming about a whole range of insecurities.
