The UK Supreme Court will on Friday hand down a judgment in a test case pitting the country’s markets regulator against insurers over how business interruption policies were dealt with during the coronavirus pandemic, it said on Tuesday.

The result of the appeal, which will be announced via video link, is eagerly awaited as it is expected to impact 700 types of policies, 60 insurers, 370,000 policyholders and billions of pounds in claims.
