Rigged Elections.
In the JULY 16, 1973 ELECTION, GUYANA'S RULING PEOPLE'S NATIONAL CONGRESS(PNC) INCREASED ITS SHARE IN 53 SEAT PARLIAMENT FROM 30 SEATS WON IN 1968 TO 34 AND WILL PROBABLY FAIL TO OBTAIN STATED GOAL OF TWO-THIRDS MAJORITY.
How did this happen?
In an environment that East Indians rejected the PNC and East Indians were the majority in the country?
