The Communist Party and the Social Democrats are among the few parties planning traditional May 1st celebrations to mark International Workers’ Day, ČTK reports. According to the news agency, the Communists will hold a public meeting at the Výstaviště fair grounds, where they have staged events over the last few years instead of Letná Park. The Social Democrats will lay a wreath marking the holiday on April 30 at Střelecký ostrov (island) - a site in Prague where the workers’ holiday was first marked in 1890. Most parties are using May 1st as an opportunity to highlight candidates and issues ahead of the elections to the European Parliament later in the month. May 1 will mark ten years since the Czech Republic joined the European Union.
