The appeals trial of former Defense Minister Akis Tsochatzopoulos and 16 others against the heavy sentences they were given last year after being implicated in a huge-money laundering network set up by the one-time Socialist strongman is to resume on October 23, court sources said on Friday.

A five-judge appeals court sat for the trial's opening on Friday but the proceedings were limited to procedural matters, not the substance of the appeals.

The 75-year-old ex-minister is currently serving a 20-year sentence at Korydallos high-security prison in Athens. His wife and daughter are serving 12-year terms.
