While in Dublin, they met health workers who were already dealing with the first cases of COVID-19 in Ireland as well as a broad range of people from the creative arts, sport, business and charity sectors.

She wrote: "On the occasion of your National Day, I would like to convey to Your Excellency my congratulations, together with my best wishes to the people of Ireland."
