There will be no delay in the implementation of locally elected police commissioners across England and Wales, the Commons has heard.
Home secretary Theresa May told MPs the new commissioners will be brought in across "England and Wales as a whole".
Under coalition plans, police authorities are due to be abolished by next May with police and crime commissioners being introduced to oversee each police force.
The first police commissioners will be elected on the same day as local elections in May 2012, and then held every four years.
Deputy prime minister Nick Clegg has backed calls from Lib Dem peers to trial the changes in pilot areas.
During departmental questions, Conservative MP Nadhim Zahawi asked what recent steps had been taken to increase the accountability of police forces to the public.
In response, May said that police commissioners would hold local police to account.
She said: "Any police and crime commissioner who is convicted of an imprisonable offence, whether or not they are sentenced to a term of imprisonment, will be disqualified from their post."
Addressing calls from senior Lib Dems for some changes to be trialled in pilot areas, Steve McCabe (Lab, Selly Oak) asked whether May will "listen to the concerns of the deputy prime minister".
The home secretary said when the legislation reaches committee stage in the Lords next week, the upper chamber would give "proper and due consideration to every aspect of the Bill".
She added: "I can also say it is our intention that police and crime commissioners will be brought in across England and Wales as a whole."
Lib Dem home affairs spokesman Tom Brake called for “robust checks and balances to challenge the action of any commissioner who exceeds their powers or seeks to interfere in operational police matters."
He urged the home secretary to “seriously consider" the calls from Lib Dem peers "to see the new accountability arrangements piloted and the checks and balances strengthened".
The home secretary replied: "I'm aware that there are some issues that have been raised in relation to the police and crime panels and how they are properly holding the checks and balances to hold the police and crime commissioners to account.
"But it is the intention that police and crime commissioners will be brought in across England and Wales as a whole."
Shadow home secretary Yvette Cooper hit out at the "American-style reform", calling for a "louder Liberal Democratic voice" in government but "they are shouting but she is not listening".
She told MPs that Lib Dem peers had proposed a two or three year pause for proper pilots to take place.
Cooper asked: "Will you tell the House whether you are indeed listening and whether you will consider amending the legislation to introduce pilots first?"
In response, the home secretary said this was not an idea with out any experience. May said it had been the last Labour government that introduced the Mayor of London as the individual responsible for overseeing the Metropolitan Police, acting as a pilot for the scheme.
Cooper said that was a "completely different arrangement and I'm not sure the Liberal Democrats will see that as the prime minister's so-called listening mode".
She added: "The so-called new business relationship is just business as usual - the Conservatives take the decisions, the Liberal Democrats take the blame."
The home secretary said it had been in the coalition agreement to commit to the introduction of directly-elected individuals to hold police forces to account, adding that there would be proper checks and balances.
