The Democratic Unionist Party has expressed fresh fury with the British government's acceptance of IRA decommissioning.
Yesterday, British minister Angela Smith told a House of Commons committee that London was satisfied with the IRA's disarmament last year.
The Independent Monitoring Commission has said "credible" reports suggest the republican movement retained some guns despite its historic decommissioning move in July.
However, Ms Smith said the British government believed any retention of arms was not sanctioned by the IRA leadership.
DUP deputy leader Peter Robinson has responded by accusing London of believing the word of the IRA above that of its own security services.
