Fine Gael leader Enda Kenny has claimed in the Dáil that the Government is losing the war on criminal gangs.
Mr Kenny was responding to yesterday's double murder of a leading drug-dealer and an innocent workman in the Finglas area of Dublin.
"Fewer and fewer of these crimes are being detected and no drug baron has been put behind bars in the last five years," he said.
"If you all know who these people are from the briefings that you get, why is it not possible for the security forces of this country to have Government backing to implement its primary responsibility to keep our citizens safe?"
The Taoiseach, Bertie Ahern, meanwhile, rejected claims from some commentators that the Provisional IRA was involved in the killing.
Mr Ahern said he had been informed that drug-dealer Martin Hyland had been associating with a former paramilitary, but said this person was not associated with the Provisional IRA either now or in the past.
