A Spanish judge has named Jordi Pujol, former longtime leader of Spain's powerful northeastern Catalonia region, as a suspect in a money-laundering probe.

Judge Jose de la Mata on Wednesday summoned Pujol and his wife, Mercedes Ferrusola, to appear before the National Court in Madrid on Feb. 10.

They are suspects in the probe into money held abroad by one of their sons. The corruption investigation is one of several involving the Pujol family.

Pujol, 85, founded Catalonia's Convergence party that governs the region. He was regional president from 1980 to 2003 and is considered the father of the Catalan nationalist movement. The secession drive has surged in recent years and now threatens to separate Catalonia from Spain to form a new independent country.
