Other ex-div stocks trading lower this morning included Hammerson, Pearson and RSA Insurance.Mining stocks were also in negative territory as metals prices slipped, with EVRAZ, ENRC, Fresnillo, Rio Tinto, Randgold, Polymetal and Anglo American all among the worst performers.

The broker said: "Despite more restrained spending, 2013/14 will be a period of price discovery, as markets move into surplus and the sector lives through the over-spend of prior years. We see downside risk to prices in H213 and this remains a challenging investment backdrop in the short run."In contrast, asset manager Schroders was performing well after Credit Suisse said that fund flow data for the UK mutual fund market showed equity inflows accelerating in February to their highest level in almost two years.Babcock, the UK engineering firm, was subdued despite saying that annual results will show "strong progress" on the previous year.
