SIR – Am I the only one who is asking the question about President Barack Obama picking on BP for causing the oil spillage, when it is American companies who are doing all the engineering, rig management, drilling and storage?

The Americans were happy enough to work as sub-contractors, accepting the money, but now they are backing off saying: “Oh no, it’s nothing to do with us, it’s all BP’s fault!”.
