"Plenty of people do just answer "No comment" to every question, even after consulting a solicitor." precisely because that's the best advice that you will get from a solicitor in the circumstances! I rather belaboured my earlier responses to this same question, because I wanted to make it understood how rarely there's any justification to arrest someone. UK LEO arrest people by default and they absolutely do not have a automatic right to arrest anyone and certainly not only to bring you in to interview.
