German leader meets former US President before Donald Trump, who is also in Europe

While sharing a stage with Angela Merkel at an event in Berlin to mark the 500th anniversary of the Reformation, the former president said the German Chancellor was one of his “favourite partners” during his presidency. 

During a wide-ranging address, Mr Obama discussed the issue of foreign aid in the developing world, which Mr Trump has suggested he could heavily reduce as part of his ‘America First’ stance. 

Mr Obama said: "If there are disruptions in these countries, if there is bad governance, if there is war or if there is poverty, in this new world that we live in we can't isolate ourselves.

"We can't hide behind a wall."

The speaking invitation to Mr Obama was made long before Mr Trump was elected. Commentators have said her decision to do so reflects her preference for Mr Obama, with whom she is known to be friendly. 

On Thursday’s meeting, the Chancellor and Mr Obama spoke on a range of political and foreign policy issues. 

"The world is at a crossroads," said Obama, speaking in front of the Brandenburg Gate. - Read More
