Oil producers were another standout sector on the upside, with Royal Dutch Shell <RDSa.L>, BG Group <BG.L>, Tullow Oil <TLW.L> and Cairn Energy <CNE.L> up between 0.3 and 1.4 percent.

"I believe everybody's endeavour is absolutely first class but nobody has a clue on how much it's going to cost and how long it's going to take. You will see equity markets bouncing like a cork in a bath in the next two to three months."
