With regard to my presence at Stormont, I was there because the Prime Minister was there. She was keen to visit Belfast. She visited Shorts and then joined the talks. There is a protocol for these matters. I had other plans for the day. As Members know, the First Minister of Wales was in town and I was due to meet him and do some other things. The protocol is that when the British Government is represented by the Secretary of State for Northern Ireland at the talks we are represented by the Minister for Foreign Affairs and Trade, but when the Prime Minister is present the Taoiseach should be too and vice versa. That is how it works.
