Derby death blaze accused trio 'rehearsed fire'

A court in Nottingham has heard secret recordings made by police of three people accused of killing six children in a fire, and how they "rehearsed" the act six weeks earlier.

The children died in the blaze at their house in Derby in May last year. Michael Philpott and his wife, Mairead, and their friend Paul Mosley deny six counts of manslaughter.
