Fears over the future conduct of the paramilitary UDA are to be raised with the British and Irish governments.
The loyalist grouping, which is the largest paramilitary organisation in Northern Ireland, decommissioned some of its illegal cache of weapons last month, but has been criticised for not completing the disarmament process.
Loyalists linked to the UDA in Londonderry and north Antrim withdrew support for the police earlier this month, sparking fears that the Northern Ireland-wide group is splintering into different factions, though this has been denied by its representatives.
UDA members have been accused of involvement in the murder of Catholic man Kevin McDaid who was beaten to death in May by a mob in Coleraine, Co Londonderry.
The organisation also faced criticism last week when 150 members took to the streets in Londonderry city.
The Ulster Political Research Group (UPRG) has insisted the UDA is committed to securing a lasting peace but has claimed that loyalist communities are not reaping the benefits of the new era in Northern Ireland and feel isolated. But yesterday East Londonderry representative for the SDLP, John Dallat, accused the authorities of “pussyfooting” with the UDA.
