An opposition MP will address the rising cost of accessing rich online data like live sportscasts and movies at a town hall meeting...The problem here is the separation of town hall and politician. As it stands, the sentence seems to suggest that the topic under discussion is the accessing of sportscasts and movies at town hall meetings. "An opposition MP will address at a town hall meeting..." or, even better, "At a town hall meeting, an opposition MP will address..." would clear up the confusion.
It may not seem like a big deal in this example, but sometimes separations like this can result in unintentionally risible effects. Take, for example, this similar sentence from a U.S. news report:
The congressman stayed after the town meeting and discussed the high cost of living with several women.
