A series of tougher sentencing measures, new criminal offences and a more balanced judicial review system will come into force when the Criminal Justice and Courts Act 2015 takes effect on 13 April.
The act contains a range of law changes, including increased prison terms for serious crimes such as certain terrorism offences and internet trolling.
It has also changed the law so anyone who kills a police or prison officer in the line of duty faces spending the rest of their life behind bars.
The act will also end the automatic release of those jailed for child rape and serious terrorism offences half-way through their prison sentence.
New offences coming into force include revenge pornography, causing serious injury by driving while disqualified, and remaining unlawfully at large following a recall from licence.
