God this is difficult, how does anyone know if someone is lying about something when it asn't happened yet? If they are being negative about the government and politicians handling of the situation then no they aren't lying but I have already agreed on that.
I don't know what you want me to say, we will know who is lying when an actual deal or no deal is done. Sorry can't make it any clearer than that.
Give me a quote (not the NHS bus) and I will try to answer it.
