"The investigation is ongoing, but unfortunately there is a chance that some of the following data may have been accessed:

"We are continuing to work with leading cyber crime specialists and the Metropolitan Police to establish exactly what happened and the extent of any information accessed."
Dido Harding, chief executive of TalkTalk, said: "We take any threat to the security of our customers' data extremely seriously and we are taking all the necessary steps to understand what has happened here. "
Ms Harding told the BBC that all 4m UK customers could 'potentially be affected' and that they would be offered one year of free credit monitoring.
