Mrs Merkel was pictured with Mr Trump and British Prime Minister Theresa May today during G7 talks in Italy.

She is known for making her infamous “diamond” hand sign, which has been branded of masonic-style and a symbol of the alleged Illuminati by conspiracy theorists.

It is alleged by believers in the Illuminati that it is a secret organisation made up of world leaders and celebrities that actually runs all world governments from behind the scenes and intends introducing a New World Order which will see just one government running the entire world.

At its most extreme, the Illuminati is allegedly a Satanic group that uses hand signals to identify members to each other.

Mrs Merkel’s use of the sign often attracts attention and comes after a Nato meeting yesterday – which is of particular significance as conspiracy theorists believe the G7 talks and NATO are Illuminati run and part of the plan to introduce a world army.

Others photographed using the hand sign in the rhombus shape have included British Prime Minister Theresa May, and European Commission President Jean Claude Juncker.

The sign is often referred to as a Merkel Diamond, due to her frequent use of it.

Mrs May was snapped imitating the ‘Merkel diamond’ while giving a speech outside the Palace of Westminster on July 11 last year.

Conspiracy theory website illuminatiRex lists the diamond sign as number one out of a top-ten of illuminati signs, with Mrs Merkel given her own section for doing it in reverse, in what it describes as the Merkel Raute.

And on the conspiracy theory forum run by David Icke, the significance of the Merkel Diamond, which has been used in political poster campaigns, has been discussed.

A senior forum member with the user name Posidon posted: “I don’t know if anyone ever noticed the Angela Merkel famous hand sign?

“I found today a new picture of it in my local newspaper, and I found curious that they use her hand sign in a political campaign.

“Diamond they say? So I ask, is every one asleep these days?

“Just the first time I saw the image, I noticed it is not a diamond at all, plus the way she placed her fingers (which is not even easy) unless you really want them to be that way does not resemble a diamond at all, but a Masonic symbol of the compass and square.

“Is every one asleep? No one sees and talks about these things, is it not evident enough?”

But, Mrs Merkel, who has led the Christian Democratic Union party for 16 years, explained the reason she makes the unusual gesture in a 2013 interview, and denied there was anything sinister behind it.
