You must remember that the referendum propaganda came from both sides. We even had a lovely little leaflet - from the Tory government - suggesting that we vote leave. So - we got representations regarding Brexit, just like in a general election. In a general election you might call each party's manifesto incitements "lies". I don't like the word "lie". For me a lie needs to have been proved not to be true. And, as Dusty sang - "Nothing has been proved".
