 The UK currently gets a 40% discount from the gross contribution which was negotiated by Margaret Thatcher in the 1980s (worth about £144 million) plus various agricultural, economic development and scientific research 'rebates' (worth approximately a further £96 million).Elements of the Leave campaign have been identified as exemplifying "post-truth politics", in which debate is framed largely by appeals to emotion rather than the details of policy or objective factual analysis.This potentially deliberate attempt to mislead the public finds relevance with Hobolt's theory, that campaigns prey on voters' insecurities.
