When you ask who? Well firstly we have elected officials on both sides of the Atlantic. I presume you voted and therefore you are aware of the individuals capabilities.
Now since we have these elected representatives, it isn't a giant leap to suggest that they be competent enough to employ folks with the best qualifications.
Unfortunately what happens, is that people are incompetent. So they are replaced. Again, I'm struggling here to understand what you are are arguing with.
In clear terms, if the government is unfit to do the job that they were required to. We must therefore, look towards alternative solutions, in my opinion, an option is to bring in duly elected members from other parties to address this issue. To form an emergency government.
