French conservative presidential candidate Francois Fillon, who is favourite to win this year’s election, will lay out on Wednesday his proposals to cut immigration to a “strict minimum” through the use of quotas, an aide said on Tuesday. Fillon, who is seen beating far-right leader Marine Le Pen if they meet in a runoff in May in the presidential election, will also urge the European Union to tighten its asylum and immigration policy to counter threats from Islamist militants.
