Jakrapob, formerly a prime minister's Office minister and until recently a leader of the red-shirt movement, asked for the postponement saying he had some business to attend to overseas.
The prosecutors decided to grant him the request because further investigation and questioning of witnesses, as well as translation of relevant documents, had not been completed, according to Kayasit Pisawongprakan, director-general of the criminal litigation division at the Attorney-General's Office.
The case against Jakrapob is in connection to a lecture he delivered, in English, at the Foreign Correspondents Club of Thailand in August 2007.
If Jakrapob fails to report to the prosecutors on June 15, his guarantors would be asked to find him or an arrest warrant would be issued for him, Kayasit told a press conference at the Attorney-General's Office.
