    The government is to carry out tests to see how toxic substances would spread if used by terrorists on the Tube.

    A harmless chemical - sulphur hexafluoride - will be used to monitor airflows at north-west London's St John's Wood London Underground station.

    Services will run as normal on the two Sundays chosen for the tests, 25 March and 1 April.
