The Christmas misery faced by the thousands of people without power in the wake of the stormy weather may continue through the week.

However, the company added: "Due to the severity of the storm damage in Kent, Surrey and Sussex it may take until the end of the week to restore power supplies to the final pockets of customers in these areas, though work is continuing to reconnect supplies as quickly as possible."
