Marine Le Pen, the leader of France's right-wing National Front party, has accused Germany of opening its doors to refugees to exploit them for cheap labour.
In a meeting in the southeastern city of Marseille, a key French destination for migrants from north Africa, she also accused Germany of trying to impose its immigration policy on the EU.
"Germany probably thinks its population is moribund, and it is probably seeking to lower wages and continue to recruit slaves through mass immigration," she said.
Le Pen also criticised European politicians for "exploiting the suffering of these poor people who cross the Mediterranean Sea. They are exploiting the death of the unfortunate in these trips organised by mafia, they show pictures, they exhibit the death of a child without any dignity just to blame the European consciences and make them accept the current situation," she said.
According to RT News, Le Pen said Germany's policy will affect the whole of the EU. "Germany seeks not only to rule our economy, it wants to force us to accept hundreds of thousands of asylum seekers.
Le Pen is hoping to stand in the 2017 presidential elections in France. In the 2012 elections, she won 17.9% of the votes, with the National Front topping the poll in the European elections last year. She is standing int he regional elections in December.
Germany is opening its doors to around 800,000 migrants this year.
France however did not have the means nor the desire to open its doors to "the world's misery," according to Reuters.
RT News said that Germany is planning to introduce a supplementary budget to free up funds for the refugees while businesses are looking to use migrant skills to close the gap in the lack of professional and skilled labour on the market.
German Finance Minister Wolfgang Schaeuble has said that hosting the fresh flows of migrants will cost the government, federal states and municipalities €10bn this year against the €2.4bn spend in 2014.
Big German businesses say can integrate refugees quickly in job market
Meanwhile big businesses are optimistic of integrating the refugees into the German workforce as an aging population and low birth rate eats away at its pool of skilled workers.
"If we can integrate them quickly into the jobs market, we'll be helping the refugees, but also helping ourselves as well, the head of the BDI industry federation, Ulrich Grillo said, according to AFP.
The news agency said that at 6.4% unemployment, the lowest level since German unification, the employers' federation BDA estimates that the country is still short of 140,000 engineers, programmers and technicians.
The healthcare and leisure sectors are also looking for qualified workers with around 40,000 training places across all sectors expected to remain unfilled this year. According to the Prognos think-tank, the shortage of qualified workers will rise to 1.8 million in 2020, and as high as 3.9 million by 2040 if nothing is done.
The influx of migrants would therefore be the answer as many of them are young and have "really good qualifications," BDI's Grillo said. Companies want the government to guarantee that the trainee they take on will not be deported. They would also like to see the requirement that businesses need to prove that there are no German candidate to fill the position before they hire a refugee or asylum-seeker to be removed.
