He said: "If Mr Kennedy does not like Socialism, we do not like imperialism. We do not like capitalism.

"We have as much right to complain about the existence of a capitalist imperialist regime 90 miles from our coast as he has to complain about a socialist regime 90 miles from his coast."

Dr Castro also announced that foreign Roman Catholic priests would be expelled and all Roman Catholic and private schools would be nationalised.

Cubans had reason to celebrate this May Day. Last month Castro's troops foiled an attempted invasion of the island by Cuban exiles supported by the USA. The invasion force of 1,300 men landed at Bah?a de Cochinos (Bay of Pigs) but was rapidly defeated.

The days that followed saw thousands of anti-Castro rebels confined in makeshift prisons and at least 600 executed. The Cuban secret service, G2, is still interrogating possible "counter-revolutionaries".

According to BBC correspondent Erik de Mauny who arrived in Miami today by plane with Cuban refugees, Castro's revolution seems to be popular with the peasants if not with the wealthier classes who have seen their land and property confiscated.

Our correspondent says the failed invasion has strengthened Castro's hold on power and could inspire socialist rebels in other parts of the Americas. "The Castro regime has created a model to which many famished eyes throughout Latin America are inevitably drawn," he reports.
