Sinn Fein's chief negotiator Martin McGuinness has said dissident republicans will fail in their attempts to destroy the peace process in Northern Ireland.

McGuinness told the BBC Radio Ulster's programme 'Inside Politics' that dissident republicans had nothing to offer the people of Northern Ireland. 'I think there is a duty and a responsibility on those people just to sitback and reflect that they're flowing against the tide', he added.

'I believe that some of them harbour the notion that involvement in these types of activities can bring about a collapse of the peace process…I believe that their strategy will fail and will fail miserably,' he said.

Mr McGuinness's comments come after police said they had uncovered an intelligence-gathering operation by dissident republicans at a Belfast hospital, and in the wake of an upsurge in terrorist activity, including a number of foiled bomb attacks.
