If you like political thrillers you will like this. In America they would call it a made for TV movie but that makes it sound cheap and nasty. Let's go with Wikipedia's "television adaption of Chris Mullin's 1982 novel" instead. Amazon has the time as 148 minutes so get comfortable before you start. It's a bit expensive on Amazon for the amount of TV you are buying but this is a case of "never mind the width, feel the quality".
My review : (5 stars) Great performances from Ray McAnally playing the working class left wing prime minister and Alec MacNaughton playing the upper class security chief determined to undermine him. I guess it is at times a working class hero fantasy, but why not enjoy it as we can't seem to get that from today's Labour Party. Look out for the very beautiful Kika Markham.
