Our conclusions are summarised in the opening section of this judgment, which we do not repeat. Whilst we accept the genuineness of the apologies proffered on behalf of MI5, the fact remains that this case has raised serious issues. MI5 gave false evidence to three courts. This was compounded by inadequate attempts to explain the circumstances. MI5 chose to maintain NCND long after it was unrealistic to do so.

The special advocates are to be commended for the central role that they have played in bringing these matters to light, as are Mr De Simone and the BBC (and its legal team). It is to be hoped that events such as these will never be repeated.

We direct that a copy of this judgment be sent to the Secretary of State for the Home Department, who has Ministerial responsibility for MI5, and to the Investigatory Powers Commissioner.
