There has been a lot of comment on whether President Obama has 'a right' to 'interfere' in the UK's domestic issues. But here's the thing, is Britain leaving the EU really only a domestic issue? The implications of such a huge decision would not only destabilise the British economy, but could have ripple effects all over the world.

Obama's communication style is so polar to that of the two EU referendum campaigns. He is warm, positive, and focused on the benefits of the UK being in the EU - not just to the UK, and the EU, but also to America and the rest of the world.

I for one welcome his intervention and hope that he continues to be a global leader long after he had left office. We need him.
