No one denies that the govt of the day has ultimate responsibility, although there is a balance of power of course - they cannot do everything they wish, and rightly so.

The point why people may think they are at least trying to sort compared to other parties is in terms of recognising the problem, coming up with policies, not campaigning against removal of foreign criminals etc. It does create an impression for some that as much as the govt takes the blame, the viable alternative would be weaker still on it.

Of course, if you don't view it as a problem, that's fair enough. It is likely as things stand that we will have a Labour govt in a couple of years or so. Will be very interesting to see what they would do differently.
