Sir, - Can someone please explain to me how, in a country whose Constitution guarantees the right to travel, and in a European Union which promotes the free movement of people, one must pay a £tax ( £5 to leave Ireland and£11 to leave Britain) when flying between Dublin and London? If the EU would deny us "duty-free" goods, surely it must allow us to travel tax free between member states? - Yours, etc., Denis Gill,
