First Minister Arlene Foster has said she is "bemused" by those critical of proposals for a bridge or tunnel connecting Northern Ireland and Great Britain. Deputy First Minister Michelle O'Neill, on the other hand, described such a project as a "pipe dream" of Prime Minister Boris Johnson. It comes after it was announced that an official feasibility study including examining potential for either a 'Boris Burrow' or 'Boris Bridge', as they have been dubbed, is to get under way. Transport expert Sir Peter Hendy - who was reappointed as Network Rail chairman yesterday - was asked by the UK Government to examine how to keep the Union connected and he has now said work should be carried out to look at a "fixed link" across the Irish Sea.
