Our speaker Dr Zeqiri is nearing the end of a short tour of Ireland speaking about these changes. Before giving the third talk on this subject talk today, 29th March 2019, thought to be the date on which the United Kingdom would leave the European Union, he wondered whether he might be able to claim political asylum in Ireland.
