The effect on stock markets has been dramatic. London’s FTSE 100 index plunged 8.5% this morning and saw its value plummet by £130bn – a fall of a magnitude not seen since the 2008 financial crash.

Other markets and the price of oil also collapsed on what’s being dubbed “Black Monday”, with a global recession now being foreseen by economists.

The World Health Organization urged countries last week to take all measures to contain the virus, but has so far resisted describing the outbreak as a pandemic.
