I'm sure, that they wish to drill oil by themselves in Northen sea. But there will be no trading volumes of oil in the North Sea in 2050. There will be no oil from Middle East, and, may be, there will be no oil from Russia (at least for Brits). May be - they will drill for oil in the shelf of Malvines (on the Sea Lion oil field). But there is a question about position of Argentina and USA.
