With regards to the external scrutiny of complaints against the police, this was strengthened by the creation, in 1985, of the Police Complaints Authority which was replaced in 2004 by the more effective Independent Police Complaints Commission and in turn will be replaced by the Office for Police Conduct in 2017. The exemplary standards of behaviour expected of everyone who works in policing were reinforced by the introduction of a statutory Code of Ethics, laid before this House in 2014.

Lastly, the introduction of directly elected Police and Crime Commissioners in 2012 has given the public a voice in shaping their local policing priorities and improved the accountability of police leadership.

Over 30 years later, policing is very different and one of my key concerns as Home Secretary is to ensure there is a policing system which works effectively and fairly now. The policing landscape has changed fundamentally since 1984 – at the political, legislative and operational levels. The same is true also for the wider criminal justice system.

There would therefore be very few lessons for the policing system today to be learned from any review of the events and practices of three decades ago. This is a very important consideration when looking at the necessity for an inquiry or independent review and the public interest to be derived from holding one.
