This weekend, Fine Gael – one half of Ireland’s governing coalition – released a “blue print” for Irish unity. Under it there would be a dedicated minister for North/South relations; a cross-party, independent consultative forum; a dedicated planning unit in the department of the Taoiseach (sort of like the cabinet office). The process – the first year of which could cost the tax payer anywhere between €3bn and €25bn, so goes accompanying research – could be funded by a sovereign wealth fund.
