Police chiefs will be forced to disclose their pay packages and all officers must reveal if they have second jobs under measures aimed at improving trust in the police, the Home Secretary has said.

A national register of officers struck off from the police will also be set up by the newly formed College of Policing, Theresa May said, while officers will no longer be able to dodge disciplinary hearings by resigning or retiring.

Mrs May said: "This country has the finest police officers in the world and the vast majority conduct themselves with the highest standards of integrity. But it is vital to ensure public confidence is not damaged when individual cases of corruption happen."

Chief constables will be required to disclose pay packages, gifts and hospitality on a national register, while all officers must provide details of second jobs. Off-duty officers and police staff are reportedly working a range of secondary roles including a vicar, pole-dancing teacher, undertaker and ski instructor. Police officers - though it is unclear which ranks will be affected - will also have to disclose contact with the media in line with Lord Justice Leveson's recommendations.

A stronger system of vetting for police officers will also be developed by the College, which chief constables and police and crime commissioners will have to consider when making decisions about recruitment.

In addition, the Home Secretary said the Independent Police Complaints Commission (IPCC) is to be expanded to deal with all serious complaints against the police. The move comes after a highly critical report from a group of influential MPs, which labelled the police complaints watchdog "woefully under-equipped and hamstrung".

Responding, shadow home secretary Yvette Cooper told MPs that many of the measures outlined were "sensible in principle".

But she said Mrs May had "not been sufficiently radical", adding she did not believe the Government was "going far enough on the IPCC".

She urged the Government to look again at replacing the Independent Police Complaints Commission altogether with a new police standards authority and a "coherent framework of standards and accountability".

She said: "She will know there is a massive problem with low morale among police officers who do not feel valued... What she's announced today is welcome and responds to many of the concerns we have raised but I do urge her to look at them again. I remain concerned they do not go far enough and they will not be sufficient to deliver what the police and the public need."
