It shows a standing Mrs Merkel, hands firmly planted on a table, staring down at United States president Donald Trump, who is seated with his arms folded.
In a statement to MPs on the summit, Mrs May praised Mr Trudeau's "skilful" handling of proceedings and said the leaders had established "common ground" on a range of matters. Although an event entirely comprising of USA allies, Trump had angered the majority of the leaders before he had even arrived, imposing trade tariffs on European and Canadian exports. At the summit, Trump refused to endorse a group deal, saying other members use unfair trade practices against the United States. "Instead, we will also act accordingly", Merkel said in an unusually combative tone.
Looking ahead to the next major diplomatic encounter with Trump - a meeting of North Atlantic Treaty Organisation alliance leaders in July - "it won't be easy", Merkel said.
Vladimir Putin wants to have a summit with Donald Trump
In an effort to counter propaganda, the G7 leaders agreed to work together to assert a "common narrative and response" to incidents.

"All of that confirms the assessment that the world is being reorganized", Merkel said. Russian Federation was thrown out of what was then the G8 after it invaded and annexed Crimea - a strategic Black Sea peninsula - from Kyiv in 2014 and later fomented an ongoing war in Ukraine's eastern Donbass region that has killed almost 11,000 people. She added that with Trump's "unpredictable" leadership and the USA turn toward isolationism, the European Union needs to hone its response to a raft of issues in an environment in which global institutions need to be "newly proven".
Other G7 countries lobbied unsuccessfully at the summit for the USA oto reverse its tariffs on imported steel and aluminium imports. He explained that "with regret", Canada will impose "equivalent" retaliatory tariffs on the USA, effective July 1.
"We spent two days producing a statement and commitments", the statement said.
