The City View: Tory party rift over windfall tax, and stock market sell-off

Today Andy Silvester talks to City A.M. reporters Jack Barnett and Nicholas Earl.

Jack unpicks the continuing stock market sell-off, one of the worst in recent memory; and Nicholas takes us through the rift in the Conservative party over the potential implementation of a windfall tax on energy companies, and assesses the viability of the tax itself.
