Lord Bramall, a former head of the British army, has now been told he will face no further action by the Metropolitan Police following thirteen months of investigation into allegations of paedophilia. The Met has so far refused to apologise for the way its inquiry, "Operation Midland", was handled.

In his first broadcast interview, Lord Bramall speaks to BBC journalist Alistair Jackson.

The programme also hears from Met insiders and other key witnesses. Their accounts raise serious questions about how the investigation was run and why the allegations against Lord Bramall were not dismissed earlier.
