It would take the Government just 24 hours to send another naval vessel to the Mediterranean - if it wanted to.
Twenty-one migrants drowned overnight on their way to Greece, sparking calls for Ireland to send more help to deal with the crisis.
We have already sent three boats, but the last navy crew returned home before Christmas.
The Irish Government has an agreement in place with Italy to assist with humanitarian missions in that sector of the Meditteranean.
However, CEO of the Immigrant Council of Ireland, Brian Killoran, has said we could return very quickly: “It comes down essentially to the Cabinet and the Minister for Defence. It can be decided really really quickly, they can do it in a day and they have in the past.
“Once it is sent out it is out for a set period of time, for a number of months. By the time that time period would be over we would have a new Government, probably at that stage and then the new Government would work on the continuation.”
