Countdown to France's conservative primary election

In France, the conservative party's primary to designate its candidate for next year's presidential election is looming. If the polls are correct, the winner could well be France's next president. While former PM Alain Juppé is comfortably ahead, his main challenger, former president Nicolas Sarkozy, is not going down without a fight. The atmosphere is increasingly tense as the seven candidates prepare to square off this week in the second of three televised debates.
