Theresa May’s European parliamentary elections could be a defining moment in the struggle for the EU's future; a continent wide clash between the forces of liberalism and populism exists - perhaps best personified by French President Emmanuel Macron up against Hungary's Viktor Orban.

Whose message is resonating with European voters?
