Beat the rush, covert today.
The Dublin accord has been ignored for years by most EU states, who have been only too happy to see migrants passing through to somewhere else in the EU. That’s how the ‘jungle camps’ came to appear in Calais and the other English Channel ports - refugees who had arrived in Southern Europe, but instead of being processed in the country they arrived in (as required by the Dublin accord) had been encouraged to travel on till they reached the UK border. There they became stuck, as the UK has never been party to the Schengen open-borders agreement, which only covers some EU countries.
