Does the Secretary of State agree that, once the channel tunnel is completed, Ireland, north and south, will be the only part of the single market that does not have a land link with the rest of the Community?

Gentleman agree that that will intensify the common economic interests of both parts of the island and should therefore lead to intensified co-operation between both Governments on those interests?
