Students mill around outside Athens University’s Department of Physics yesterday after casting their votes in student elections, which were held in universities and technical colleges across the country. Participation was believed to have reached the high level of last year’s polls, when 140,000 students, or 75 percent, cast their ballots. However, elections for two departments of Athens’s technical college had to be postponed after the electoral registers were found to include the names of 400 graduates. The overall election results are to be announced today.
