"Who told you you have it in the UK?"
Remaining silent is a double-edged sword.
If the police are on a "fishing expedition" then they need you to answer questions to give them something they can portray as "evidence" of involvement in a crime - or to incriminate the main subjects of their investigation.
If you are innocent - and the police have nothing they can claim as solid evidence for a charge - then a solicitor may advise you to remain silent.
However if they have apparently solid evidence that you can refute then it may be best to do so. A relatively recent law change allows a court to take a dim view of your later refutation at a trial.
