As there are a fixed number of companies in each index, a "rebalancing" through deletions and additions must take place.

Russ Mould, investment director at AJ Bell, said that in the event of its demotion M&S chairman Archie Norman and chief executive Steve Rowe must "not try to manage the share price" but rather, continue to focus on the retail giant's assets.

He said: "The issue is their strategy will need time, especially when it comes to the Ocado deal, and investors have become impatient."
