With Have I Got News For You now the satirical equivalent of a dad at a disco, the need for an acerbic outsider to square up to the establishment has never been greater. While British TV is yet to find anything as punchy as HBO's Last Week Tonight, but Guy Davidson and Dan Clarke (aided by performers including Emma Sidi and Jon Pointing) will attempt here to blend sketches and remixed news footage into - if we are lucky - a chunky satirical soup. If we are not, expect the same insipid gruel we have been served many times before.
