(Reuters) - British blue-chip stocks fell again on Wednesday as Marks & Spencer tumbled after announcing a rights issue to fund an online food joint venture with Ocado, while plans for a cash call knocked Metro Bank to an all-time low.

The blue-chip bourse, which earns a major chunk of its earnings in dollars, was also dragged down by a stronger pound. Sterling had rallied in the previous sessions as hopes grew that Brexit maybe delayed.
