"If asked to do so, you must give your name, address, date and place of birth and nationality to the officer. You may also be asked for an explanation of your behaviour. If you give false information or refuse to answer, you are committing an offence for which you could be arrested and charged."
They have the right to make you identify yourself but have less limited rights about searching you and your possessions. However with Patel in charge I expect police rights will only go one way.
