Ravi Singh is representing his client, Tracey Bloodman. He is defending her against a charge of theft of items from a shop. Tracey originally told Ravi that she was not guilty of the offence but later, during a meeting with Ravi, Tracey confides in Ravi that she did actually take the items and is guilty of the theft. However, Tracey is insisting that she still wants Ravi to enter a plea of "not guilty" at the court hearing. Explain what Ravi's response should be to Tracey's instruction that he should enter a "not guilty" plea
