A Cuban political leader took issue yesterday with reports in The New York Times to the effect that the Cuban revolutionary strike has collapsed.

In a statement issued here, Jose P. Iriarte of the Organizacion Autentica de Cuba, an Opposition group, said that a truly revolutionary strike against the Government of President Fulgencio Batista would be called later.

Senor Iriarte contended that since Fidel Castro, Cuban leader, and his Twenty-sixth of July Movement represented only a fraction of the revolutionary forces in Cuba, the failure of the strike initiated by Senor Castro April 9 should not be regarded as a revolutionary "collapse."

In an April 14 dispatch from Havana, Homer Bigart, a New York Times correspondent, attributed the "collapse of the Cuban revolutionary strike" to "unrealistic planning, poor coordination and shockingly inadequate communications."

Senor Iriarte objected to Mr. Bigart's description of what had collapsed.  He said the description was "completely unfair to the Cuban people, to the American people and to the people of the free world at large."

Senor Iriarte's party is headed by Dr. Carlos Prio Socarras, former President of Cuba, now an exile in Miami, Fla.
