Parliament

I really don't know, but I'm sure that if the Gibraltar First Minister were to request you to stand; out of courtesy you should get on your feet without undue delay. 

Thats very good I shall use it my inauguration speech.

I however shall demand people clap when I enter a room.

The political scene here seems to be more like a dictatorship as there is no real way of opposing what the Chief Minister wants to do.   To answer your question perhaps some form of coup would be your quickest route to power.    The queue for a Gib card and the fact that summer hours are now in will delay any other more orthodox route to power for at least 30 years.
