PM 1to1 is likely to attract large audiences. It would be a mixture of politics and reality TV. As it would be live and unedited, it would be more real than reality TV!
Each month, ten members of the public would have five minutes to talk about anything they want with the PM. It is noteworthy how presently any footage of a member of the public managing to have some sort of conversation with a prime minister, usually at election time, tends to go viral.
Apart from the normal political interest in anything the PM has to say, the programme would reveal a great deal about the personality of the PM. How do they relate to members of the public who may be hostile or well-disposed or angry or shy or knowledgeable or hard to understand or whatever it may be?
