France is to clear out some migrant tent camps, impose quotas for migrant workers and deny newly arrived asylum seekers access to non-urgent healthcare, in a drive to show voters President Emmanuel Macron is heeding their concerns about immigration.

"We want to take back control of our immigration policy," said Prime Minister Edouard Philippe as he unveiled a package of measures on immigration.

"That means when we say yes it really means yes, and when we say no, it really means no."

Opinion polls show voters are worried about the issue, driving support for far-right leader Marine Le Pen, likely to be Macron's main opponent in the next presidential election in 2022. Ms Le Pen dismissed the new measures as political posturing.

"This is smoke and mirrors. This is an electoral move," she told Europe 1 radio.
