"Dissident republicans are targeting the Conservative Party conference, a Tory MP has claimed.
Patrick Mercer, a former Army officer, claimed his information came from his sources in Northern Ireland.
"One of the aspirations undoubtedly is to attack the Tory party conference," he said.
"I don't think they have that capability but they're talking about it," he said.
A recent upsurge in attacks by dissident republican groups has included attempts to kill police officers in under-car booby-trap bombs and a 200lb bomb which exploded outside a police station in Londonderry.
Mr Mercer said: "Over the last three or four weeks there have been several very determined efforts to kill in Northern Ireland.
"There are three groups in Northern Ireland which are planning to do something to catapult themselves into the headlines before the party conference season."
