Narrowing down ideas

I have decided, after my focus group yesterday and considering all my plot ideas, that I will be considering two of my four original ideas for my radio play. Here are those ideas:

• A Prime Minister's popularity is falling. In an effort to 're-connect' with voters, he goes on tour with heliarious consequences and as a result people take them to their hearts.

• A Foreign Secretary is at an international summit where comical bad things keep happening to him. Upon investigating, he becomes paranoid that he is part of an international conspiracy. However, it is actually his assistant causing all the trouble.

One of the main reasons for eliminating the other two ideas is that they are too complex for the audience to follow in a five minute drama.
