theguardian.com – Almost 200 families of people killed by the security forces in the Northern Ireland Troubles are accusing David Cameron’s government of redacting and covering up sensitive files into their deaths.

In an advertisement published in the Guardian on Monday, the 180 families say the prime minister has reneged on a promise at the time of the Bloody Sunday report when he said there would be a new regime of openness regarding controversial killings by the British state in the conflict.

In the advertisement, issued through the Pat Finucane Centre in Derry, the relatives express concern that files belonging to police, the military and the Security Service relating to these deaths are being censored before being seen by the families’ legal representatives.
