An MEP and former leading member of Greece's banned neo-Nazi Golden Dawn movement, arrested in Belgium, has challenged moves to send him home for imprisonment, prosecutors said Wednesday. Ioannis Lagos was held on a European arrest warrant in Brussels on Tuesday, immediately after the European Parliament voted to strip him of his immunity. But, brought before a Belgian magistrate on Wednesday he challenged the move to send him to Greece to serve a 13-year jail term, deputy public prosecutor Katrien Meulemans said. mad/dc/rmb/mjs
