El Salvador's five-man junta will announce a new cabinet early this week that sources said is composed primarily of liberal politicians and technocrats expected to bring the new government additional support among centrist and moderate leftist groups.

Liberal politicians said yesterday that the reaction of rightist military and private sector organizations to the Cabinet will provide an initial test of their acceptance of the junta itself, Washington Post Correspondent Karen DeYoung reported.

With few exceptions, the reported Cabinet selections thus far are notable for their ties to traditional opposition parties and lack of association with the previous government.

Ruben Zamora, expected to be the new minister of the presidency, is an ex-seminiarian, an attorney and a doctor of political science who headed the national university's political science department.

Sources said the appointments will also include Alberto Hart, El Salvador's most prominent housing and urban development specialist, as planning minister; and Manuel Enrique Hinds, a Chicago-educated economist as head of the Economics Ministry.

Hector Dada, a Christian Democrat and head of the economics department of the Central American University here, will become foreign minister, sources said.

Militant and Marxist groups, most of whom have denounced the recent coup as a "military maneuver" to continue the former government under different high-level leadership, have not commented on the proposed Cabinet.

But militants of the Marxist People's Revolutinary Bloc occupied the San Salvador cathedral to reaffirm their opposition to the new junta.

The directorial commission of the Christian Democrats voted to participate officially in the new government. They and other opposition parties had refused to name candidates for congressional elections President Carlos Huberto Romero had scheduled for next March.
