A newly-empowered police watchdog will begin investigating complaints against the police next year, Home Secretary Theresa May will say later.
The expansion of the Independent Police Complaints Commission is “on track”, she will tell the College of Policing.
Mrs May pledged in February that the IPCC would be given more powers.
It came after a report by MPs said the body was “overwhelmed, woefully under-equipped and failing to get to the truth of allegations”.
The plans also followed concern over force standards in wake of the phone-hacking scandal, the handling of the Hillsborough disaster, and the sacking of several senior officers.
The IPCC’s expansion will allow it to take on all serious and sensitive allegations made against officers.
In February, Mrs May said it would create a stronger and more consistent system of vetting. She also outlined a new code of ethics for the police force in England and Wales.
In a speech to the College of Policing later, Mrs May is expected to say some forces, as well as police and crime commissioners, had attempted to resist the transfer of resources required for the IPCC to take on a bigger role.
“I want to say to them very clearly that the events of last year prove overwhelmingly the case for a beefed-up IPCC and that is what I’m determined to deliver.
“The expansion of the IPCC is on track and the IPCC will begin to take on additional cases from next year,” she is expected to say.
She is also expected to hail the College’s new Code of Ethics as equivalent to the Hippocratic Oath of policing – setting down standards which all officers will be expected to follow.
New powers were given to the IPCC before it investigated allegations that police officers were involved in a cover-up of failings following the 96 deaths at the 1989 Hillsborough tragedy.
The home secretary is expected to say further powers could be given to the commission if required in the future.
One in four officers faced complaints between 2011 and 2012.
