SAO PAULO, Jan 29 (Reuters) - Former Brazilian President Luiz Inacio Lula da Silva and his wife will testify next month in a money-laundering investigation of beachfront apartments that may have been used as bribes for members of the ruling Workers' Party.
Public prosecutors in Sao Paulo state said they suspected Lula's family might have owned one of the apartments in the Solaris complex in Guaruja. Lula's lawyer has denied the allegations.
Investigators ordered searches and arrests on Wednesday in the latest phase of Brazil's largest-ever corruption probe, looking into whether builder OAS SA used the apartments as bribes in a corruption scheme at state-run oil company Petrobras .
Lula's legacy has been tarnished by the corruption scandal ensnaring key aides and associates in his Workers' Party and adding to the political crisis that threatens to unseat his hand-picked successor, President Dilma Rousseff. (Reporting by Eduardo Simoes; Editing by Lisa Von Ahn)
