The Prime Minister has been asked to ensure full co-operation with a fresh inquest into the loyalist murder of Gerard Slane - shot dead at his west Belfast home more than 20 years ago.
With David Cameron in Northern Ireland yesterday, Mr Slane's widow Teresa and the support group Relatives for Justice demanded "the full co-operation of his Government".
"This extends to providing all the necessary documentation, including the Stevens Report, and ensuring that all members of the intelligence services and armed forces who have relevant information concerning Gerard's murder are also available to the court," Mark Thompson of Relatives For Justice told the Belfast Telegraph.
Father-of-three Mr Slane was killed on September 23, 1988 by the UDA.
In a statement his son Sean said: "We know that there are lots of families from both sides of the community that need answers and it is difficult for them especially when there exists criticisms about 'raking over the past' and the costs.
"If costs are an issue, I simply say dispense with all this and publish the Stevens Report."
