Ivanka Trump reportedly filled in for her father and President of the United States Donald at the G20 summit table today.

A Russian negotiator tweeted a photo of Ivanka sat in Donald's seat next to Theresa May.

But it was not deleted fast enough. In this glorious modern age, split-second screengrabs mean not much can be hidden from the internet.

Even heavyweight political commentators got involved.

Quoting Lukash's now-deleted tweet, Michael McFaul, former U.S. Ambassador to Russia, tweeted: "This is strange. Very strange."

Most were alarmed that it was downright undemocratic - after all, many are sceptical about Donald Trump's qualifications to be President, but at least he had votes cast for him.

Spot the odd one out...

A few people had some bright ideas.

While others pointed out a healthy dose of hypocrisy.
