Before Professor McNulty answers, I note that in a written response to a parliamentary question in July 2018 the cost of full membership of CERN was quoted at approximately €15 million. This committee has discussed CERN before and we heard figures like that. I want to put that into the mix and ask the witnesses to debate the two different prices. I see from the map that there are member states, associated members and then countries with co-operation agreements. That probably determines the price.
