Embattled President Jacques Chirac sought to woo back sceptical voters on Thursday by vowing to defend French industry in light of a rumoured takeover bid for food giant Danone. Chirac, whose popularity has slumped close to all-time lows, said he would be "vigilant and mobilised" should U.S. drinks firm PepsiCo mount a takeover bid on Danone. "France's priority is to defend its industrial competitiveness and the strength of its businesses," Chirac said during a two-day visit to Madagascar, after three top ministers all vowed to protect France's national interests. Analysts say Chirac's remarks reflect his need to convince voters he will do all he can to protect French jobs -- a key issue after many voters said they rejected the European Union's constitution in May to voice their anger over high unemployment.
