Far-right parties have made gains in Germany, France and Italy - the EU's biggest member states.
Their success has already led to a fall in the value of the euro as markets anticipate turbulent times ahead. President Macron's high-risk response to his Renaissance party losing to Marine Le Pen's National Rally was to call a snap election for the French parliament.
Niall Paterson talks to Sky's Europe correspondent Adam Parsons about what's behind the far-right surge and Macron's decision.
Plus, the Liberal Democrats launch their manifesto saying it's fully costed. Niall asks economics editor Ed Conway if their numbers add up and he talks to Jon Craig, Sky's chief political correspondent, to find out more about their policies.
