French Interior Minister Gérald Darmanin warned on Friday of potential unrest in France following the upcoming parliamentary elections.
"On the evening of the first round and no doubt on the evening of the second round when the final results are announced, the ultra-left and ultra-right can take advantage of this to sow a form of chaos," the minister told broadcaster France Info.
He responded to questions posed by the broadcaster based on a 10-page memo it obtained that his ministry distributed to police prefects.
In the document, Darmanin highlighted a "context shaped by several security risks" and the concern over "targeted destabilization actions."
France's parliamentary elections are being held in two rounds on Sunday and on July 7.
French President Emmanuel Macron called snap National Assembly elections earlier this month in response to the defeat of his liberal forces in the European elections and a resounding victory for the right-wing nationalists.
In the France Info interview, Darmanin also warned of "extremely serious unrest" after the political summer break from September onwards, should the far right or far left come to power.
If one of the two camps begins to implement its economic plans, France could face pressures on the financial markets, he said.
The autumn is traditionally a period when unions in France organize rallies to voice social demands or protest government plans, adding another layer of potential tension.
