Conservative MP Bernard Jenkin, who chairs the Commons public administration select committee (PASC), has said the "devastating" police watchdog analysis of recording crime statistics have corroborated with his committee's own findings.
Like PASC, HMIC is 'seriously concerned' about 'weak or absent management and supervision of crime recording and serious sexual offences not being recorded.
The police have failed to prosecute offences when they should have done. This both under-records crime and over-states clear-up rates.
HMIC says the same. They also accept that it is 'difficult to conclude that none of these failures was the result of discreditable or unethical behaviour'.
The National police lead for crime statistics, Chief Constable Jeff Farrar has said that officers join the police "motivated by a desire to protect the public" and not with an "intention of recording crime inaccurately."
This comes after reports by a police watchdog that say police may be failing to record as many as one in five crimes.
Chief Constable Jeff Farrar said: "It is clear the service has not always met the standards of data quality that the public expects.
"The service is already actively addressing many of the weaknesses identified by the report: we're reviewing the way we record sexual offences across the country and we're working with the College of Policing to implement the Code of Ethics, which highlights the need for ethical recording," he said.
The consequences of police officers not properly recording crimes are "serious", the head of the police watchdog has said.
The Chief Inspector of Constabulary, Tom Winsor, was speaking after a report claimed officers may be failing to record as many as a fifth of crimes.
The consequences of under-recording of crime are serious, and may mean victims and the community are failed because crimes are not investigated, the levels of crime will be wrongly under-stated, and police chiefs will lack the information they need to make sound decisions on the deployment of their resources.
The Home Secretary has hit out at the police after a series of inspections showed officers may be failing to report as many as one in five crimes.
Theresa May said the inspection from Her Majesty's Inspectorate of Constabulary showed "unacceptable failings by the police".
She warned that the police could now start recording more offences, leading to a spike in headline crime statistics, but she insisted this did not mean crime was going up.
"It is quite possible, once HMIC has completed its work on recorded crime statistics and made recommendations on how the police need to improve, that we will see an increase in recorded crime," she said in a statement.
"If that increase is driven by improved accuracy in the recording of crime or more victims reporting crime to the police, we should welcome it. Such an increase would not mean that crime itself is rising," she added.
As many as one in five crimes could be going unrecorded by police, a major report has found.
An investigation by Her Majesty's Inspectorate of Constabulary (HMIC) also found some offenders were being issued with 'out-of-court disposals' such as a caution rather than being prosecuted.
Inspectors looked at 13 different forces and said they could not rule out "discreditable or unethical behaviour" from officers for the failure to record some crimes.
Theresa May has said controversial police powers to stop and search are to be revised.
The Home Secretary wants to cut misuse of the powers, which may have been used illegally a quarter of a million times last year.
ITV News UK Editor Lucy Manning reports.
The Home Secretary told the House of Commons she had "long been concerned about the use of stop and search".
Theresa May said: "While it is undoubtedly an important police power, when it is misused stop and search can be counter-productive
"First, it can be an enormous waste of police time. Second, when innocent people are stopped and searched for no good reason, it is hugely damaging to the relationship between the police and the public. In those circumstances it is an unacceptable affront to justice."
Police will face disciplinary action if they fail to stick to a revamped code of practice for using controversial stop and search powers, the Home Secretary has told the House of Commons.
Theresa May told MPs that fresh legislation on stop and search will only be introduced if forces fail to comply with the new guidance. She said officers will need to pass a rigorous new assessment of how stop and search powers are used.
If they do not pass the test they will be stripped of being able to use the powers. Her Majesty's Inspectorate of Constabulary (HMIC) found 27% of stop and searches examined by the watchdog did not contain reasonable grounds for suspicion.
The mother of Azelle Rodney, who was shot dead by a police marksman nine years ago, has criticised the Crown Prosecution Service for the "intolerable" delay in making a decision on criminal charges.
Susan Alexander has written to the CPS telling them that "no mother should have to go through this".
Mr Rodney was shot six times when officers stopped a car he was travelling in with two other men in Edgware, north London.
The officer who fired the fatal shots, known only as 'E7', lost an appeal against a public inquiry finding that he had used excessive force when he shot Mr Rodney.
His lawyers argued that the police had intelligence that the men in the car were carrying machine guns and that the officer had fired because he thought Mr Rodney was about to shoot him.
The Crown Prosecution Service has charged a police officer with distributing illegal images on his phone. In a statement, Deputy Chief Crown Prosecutor Jenny Hopkins said:
We have been asked to review a file of evidence submitted by the Metropolitan Police Service’s Department of Professional Standards concerning alleged offences under the Obscene Publications Act. Following a review of the evidence, we have concluded that James Addison, a police constable in the Diplomatic Protection Group, should be charged with 11 offences.
It is alleged that between 17 February 2013 and 6 June 2013, PC Addison distributed moving images via his mobile telephone, contrary to section 2(1) of the Obscene Publications Act 1959.
