Britain's FTSE 100 was marked 0.3% lower in the opening minutes of trading in London, led to the downside by basic material and energy sector shares and a stronger pound, which traded past the 1.33 mark against the U.S. dollar.

Global oil prices were active in overnight trading as investors trimmed prices from recent two-and-a-half year highs amid signs that U.S. production increases may at least partially offset speculation that OPEC will extend its agreed production cuts from March to the end of 2018 when leaders meet later this week for a major summit in Vienna.
