This coming into the public domain does not suit the Govt.
They are going down a path (Brexit) on the basis of a referendum, the validity of which is called into question by these revelations. When you throw in the Russian botts and money from questionable sources (breaking all electoral rules) it starts to look like the referendum result may not be relied upon. Very embarrassing !
The above is the version kind to the Govt. Another version might be that members of the Govt knew and were complicit in the actions of CA.
The stench is only just beginning to percolate.
