With Greeks preparing to decide on whether to accept a bailout from the EU and the IMF in a crucial referendum on Sunday, economist Martin Armstrong sensationally claims that the troika is planning to rig the vote.

Armstrong quotes Greek Finance Minister Yanis Varoufakis, who accused the EU of forcing Greece to close banks "for the sole purpose of blackmailing" and "Getting a 'Yes' vote on a non-sustainable solution that would be bad for Europe."

Armstrong, who is known for successfully predicting the 1987 Black Monday crash as well as the 1998 Russian financial collapse, asserts that EU leaders are desperate to prevent Greece from leaving the Euro because it could grease the skids for France taking the same course. Such an eventuality would also bolster the chances of Britain leaving the EU altogether and could push Greece into the arms of Russia.

The situation is so dire, that power brokers may even rig the referendum to get the outcome they want, claims Armstrong.
