Former President Nicolas Sarkozy’s political party, already enfeebled by a chaotic national leadership election last year, faces further ridicule in a Paris town hall primary election which ends tonight. An “online-primary”, claimed as “fraud-proof” and “ultra secure”, has turned out to be vulnerable to multiple and fake voting. The four-day election has also the exposed the poisonous divisions created within the centre-right Union Pour un Mouvement Populaire (UMP) by the law permitting gay marriage which took effect last week. France’s first “electronic election” had been expected to anoint a rising star of the moderate right, Nathalie Kosciusko-Morizet, 39, as the party’s candidate in the election for mayor of Paris next spring. The former environment minister, known as “NKM”, was runaway favourite to win in the first round until she abstained in the final parliamentary vote on same-sex marriage in late April. … What was already shaping up as a tense and close election was thrown into utter confusion at the weekend. Journalists from the news site Metronews proved that it was easy to breach the allegedly strict security of the election and vote several times using different names.
