A GANG who masterminded England's biggest cannabis factory on a Hampshire farm were today starting prison sentences totalling 25 years.

Southampton businessman Allen Taylor, who ran two firms selling 4 x 4 vehicles, was jailed for seven years for his part as ringleader in the potentially hugely-profitable scheme.

His younger brother Alex was sentenced to three years behind bars.

Police who uncovered the sophisticated operation estimate that it could have worth up to £1.5m a year.
