Shanghai copper down

The most-traded copper contract on the Shanghai Futures Exchange closed down 1.2 percent to 47,320 yuan a tonne on Tuesday as a firmer US dollar pressured the market, but expectations of strong demand in top consumer China put a floor under the market.
The pound hovered near three-month lows versus the dollar on Tuesday and stocks were mostly weaker as investors waited for British Prime Minister Theresa May to lay out plans to exit the European Union amid fears Britain will lose access to the single market.
