Dissident Republicans are "hell-bent on turning the clock back" on the peace process, shadow Northern Ireland minister Ivan Lewis told Daybreak, after Downing Street warned that suspicious packages found at armed forces recruitment offices bore "hallmarks of Northern Ireland-related terrorism".
"Let's make it clear they speak for nobody in Northern Ireland in wanting to turn the clock back on the peace process," Mr Lewis said.
"They are hellbent on turning the clock back to the violence. Whatever the difficulties in Northern Ireland, and there remains some around parades and the flags and the past, nobody on any side of the sectarian divide wants to turn the clock back to the troubles and the trauma of the violence."
