We need a common European tax policy that closes these tax loopholes. We need a common European social policy that prevents social dumping.

The German chancellor has completely failed to convey that throughout her years in power. We need a re-start for Europe.

If we want to defeat Islamic State, we first have to arrive at a cease-fire agreement in Syria.

Primary responsibility for Brexit lies with British conservatives, who took an entire continent hostage.
