THE ban on drivers using mobile phones in transit put Armour Group in the fast lane. It is the UK leader in telemute leads, used by the main mobile networks when installing hands-free car kits. More than 2m kits have been fitted, helping interim pretax profits to jump to £1.3m from £368,000, on turnover up from £6.9m to £13.8m. Analysts forecast £3.1m for the full year. Shares eased 1/2p to 80p. Cheap.
