Yes, Prime Minister works best for very advanced learners who can follow fast and complex English. The dialogue moves at around 141 words per minute, with frequent back-and-forth exchanges. Learners will hear plenty of useful natural English, but some lines may still require a second listen. Also, jokes, quick reactions and casual exchanges are a regular part of the dialogue. The complexity of the plot makes listening more challenging because learners also need to keep track of what is happening. For learners around C1/C2, this can be a practical choice for practising everyday conversation and informal expressions.
