The Prime Minister vowed to pay the huge sum to improve security around the port while taking in more child refugees to ease the numbers of people displaced following the dismantling of the ‘jungle’ migrant camp.
But experts have claimed it will do nothing to help solve the situation as hundreds of refugees refuse to be processed through official channels in France.
Christian Salomé, head of the Auberge des Migrants charity, said: “These reforms will do nothing to improve the situation for migrants in Calais.
“They won’t encourage people to go into the reception centres, instead it will just make them take more risks and make more dangerous attempts to cross the border.”
Some 75 percent of the 500 refugees in the region reportedly refuse to be processed in immigration centres according to French government figures –leaving constant police evasion or desperate and dangerous attempts to enter Britain as their only options.
Migrant reception centres use fingerprint scanning to log where a refugee may have entered the EU.
This then allows them to then return them to the first country they entered and apply for asylum there under the bloc’s Dublin agreement.
Politicians in France have been quick to warn President Emmanuel Macron that revisions to the Tourqet Treaty, agreed with Mrs May last week, will not resolve the issue on the border.
French official Fabien Sudry told Mr Macron: “It’s a major problem for us.
“The vast majority refuse to have their fingerprints taken.
“This would lead us to start the process of returning them to the country of origin, which is much more complicated.
“Fingerprints are the only way of starting it.”
Xavier Bertrand, the president of the Hauts-de-France region, said: “Only the name of the Le Touquet treaty has changed.
“The situation in Calais will stay exactly the same, with all its problems and dramas.”
Many displaced migrants have taken to sleeping in underpasses and woodland around the city, regularly moving to escape the risk of encountering the police.
Speaking to the Telegraph an Eritrean man, who gave his name as Samuel, said: “If we see the police we run away.
“Some nights, police come and beat us or use tear gas.
“If the police come then you run away and you don’t sleep. It’s bad.”
