GlaxoSmithKline (>> GlaxoSmithKline) posted its worst performance in nine years, sinking 5.5 percent as the prospect of the group engaging in a consumer health business deal worth some $15 billion sparked investor fears of a dividend cut.

"Investors remain focused on the safety of the dividend," said Leerink analyst Seamus Fernandez.

Antofagasta shares posted the second worst performance, falling 4.4 percent after its copper production forecast and third quarter results disappointed investors.

Other miners such as BHP (>> BHP Billiton Plc), Rio Tinto (>> Rio Tinto) or Fresnilo (>> Fresnillo) also slid, down 2.9 percent, 2.6 percent and 2.3 percent respectively.

On the few stocks on the positive side, British American Tobacco (>> British American Tobacco) grew 0.4 percent after saying that it sees revenue from "next generation products", such as e-cigarettes and vaping products, doubling to more than 1 billion pounds next year.

British bank Lloyds (>> Lloyds Banking Group) also made it to the green, up 0.8 percent after reporting third quarter earnings.
