prison-industrial complex

[…]if we pursue the privatisation of prisons, a large industry will develop. Over the past two or three years many hon. Members have been lobbied by the private prison groups. They are already organised and are paying political consultants and lobbying companies. Some of them have paid Conservative Members—not Labour Members [to lobby for private prisons.¶The prison industrial complex already existed and Conservative Members were taking the King's shilling years ago in respect of that professional lobby.
