All British troops involved in fatal incidents during the Troubles in Northern Ireland are to face a fresh criminal investigation, it has been reported.As many as 1,000 former servicemen, many in their 60s and 70s, will be investigated and could be treated as murder or manslaughter suspects as part of a multi-million pound review.The Police Service of Northern Ireland’s Legacy Investigation Branch will look at all 238 fatal incidents in which 302 people, many of them terrorists, died.

Others were handed “letters of comfort” by Tony Blair promising they would never be prosecuted. Tory MP Johnny Mercer, a former Army officer who has campaigned against the hounding of troops by the legal system, described the review as a “brand new witch hunt”.
