And no, I don't have a lot of knowledge of the LSE - but does my time on the IPE back in 1990 when I was involved with creating hedging mechanisms using No 2 Oil for Jet futures (as despite strong lobbying the combined volumes of potential jet trades through the IPE, NYMEX and the CME were apparently not worth the while of those exchanges to set up a jet trading floor) worth something to you?
