I had not believed a word that the BBC reporters state after Sarah Smith admitted to me in an email shortly before the 2016 EU referendum that she is told what to say by researchers. This means that these researchers are pushing their own political views and agenda by getting BBC reporters to state hat they are told to say even if it is wrong.
In the case of the duff report by Sarah Smith her researcher was a Remain supporter as the incorrect information stated by Sarah Smith made out that the EU was a lot better than they really were.
