Fixed-term Parliaments Bill

My Lords, would the noble Lord care to ponder on the thought that the British public might wish to have a Government that is taking into account public opinion once every four years as opposed to once every five years? His argument is that the fifth year is the year when the Government of the day is having regard to the next election and public opinion. In my experience, the public form an opinion about Governments fairly quickly and to ask them to wait for five years before expressing that view is rather long.
