Promising clinical data from Pfizer and BioNTech help the index to a 28bn one-day gain

Optimism that a mass rollout of Covid-19 vaccines will lead to an economic recovery lifted stocks in London again on Tuesday, to their highest closing level in over four months.

London's FTSE 100 index of blue-chip shares rallied by nearly 1.8% to finish at 6,296 points, the highest close since 23 June. This added 28bn to the index's value, taking its gains so far this week to nearly 100bn after it surged 4.6% on Monday on news of a vaccine breakthrough.
