French President Emmanuel Macron faced the first grassroots revolt from within his own camp today when hundreds of activists asked a court to halt voting on new rules for the political party that helped him win power in May. <br/><br/>The challenge came on the heels of a poll showing a slump in the 39-year-old president's approval rating after a series of politically testing events, including a budget row that prompted the head of the army to quit. <br/><br/>Members of Macron's Republic on the Move party (LREM), which espouses a break with old ways of doing politics, are taking part in an electronic vote on new party statutes that is due to end on July 31. <br/><br/>The activists involved in the legal challenge say they number about 1,200, a fraction of the LREM's total membership of more than 375,000, but they reveal a degree of discontent in the ranks with Macron's forceful style of leadership. <br/><br/>The group says the disputed statutes would limit decision-making and future internal ballots to the LREM's upper echelons.
