Hannan, as MEP since 1999, is well-placed to critique and provides an impassioned and persuasive piece for Brexit. However, despite generously filled with quality references, statistics and personal experiences, note warily that it reaches for anecdotal descriptions and sweeping accusations a little often. Along with Hannan's background, it is sufficient to foment doubts on veracity and interpretation at times. Regardless, it provides arguments backed up by numbers and research of quality above and beyond that which dominated the airwaves leading up to Brexit - and Britain would have been better for it, had there been more of these leading up to the referendum.
For example, he criticises EU regulations and bans on health products and supplements as example of big pharma profiteering, with his view being "most of these products are harmless placebos", in a somewhat condescending and alarmingly dismissive manner for a matter of scientific and health considerations. This aura surfaces through the book - which is filled with various pro-Brexit (such as port regulations destroying the british industry) examples but spanning little more than several paragraphs, and the language peppered with stigmatising generalisations such as "cronyism" by "Eurocrats".
However, the text excels on trends and economic numbers that support the position that EU is more heavily dependent on the UK than it cares to admit; the UK has strengths that may succeed beyond the regulatory overreach and limitations of a bloc that tries to be more than a trade bloc (whose overreach already affect sovereign parliamentary powers, but many are still unaware of); and that British economic success outside of the EU is sufficiently probable to tip the scales on favour of Brexit. This rises above the noise of immigration and racism that has simplistically tarred the debate, often unfairly in favour of Remain and against the perceived lesser educated, and more aged support base of Brexit. The importance of economics, policy, procedures and parliamentary powers are concisely parsed for the masses to decide, and not avoided and couched in simplistic catchphrases without citation. And this is where Vote Leave succeeds.
Readers should ultimately note that Hannan is a dyed in wool Conservative, columnist and former speech writer the likes of William Hague - that makes him a propagandist, and a very eloquent one, in the neutral sense of the word. He is also a senior member of the Vote Leave campaign, so his text is aimed to persuade, not to provide an impartial paper on the subject. As he excellently puts to a pro-Remain Labour MP Emma Reynolds (whom he demolishes on a BBC news debate readily available on the web), he can see arguments for Remain, but it is not his job to tell what they are.
That is what you will find in Vote Leave.
