The EU has demanded Greece work faster to process asylum applications from refugees on the islands, and send rejected candidates back to Turkey.
But processing on the islands has not been going quick enough because, according to local media, the EU has not sent enough asylum experts.
Luise Amtsberg, the refugee spokesperson for the Green faction, said: “The conditions on the Greek islands are a shame for Europe.”
Greek Prime Minister Alexis Tsipras has also hit out at the handling of the Europe migrant crisis, and has blasted the lack of solidarity between EU member states.
The existing treaties to deal with the refugee crisis “must be respected by all,” said Tsipras, as he called for financial cuts for those members who did not follow migrant quotas.
His comments echo those of Italian prime minster Matteo Renzi, who issued an ultimatum to rebel countries to pull their weight in the migrant crisis or face the financial penalties.
Yesterday it was reiterated by secretary Benedetto Della Vedova, who said: “If you challenge the EU decision on migrants, with or without a referendum, someone will also challenge decisions regarding the budget.”
Hungary’s president Viktor Orban has threatened to sue the EU in defiance against the quotas, following a referendum which overwhelmingly rejected the EU proposals.
He added: “There will be a serious legal debate on whether a foreign population can be imposed on the people of an EU member state against its will.
“This will be a big battle, and for this we need the amended constitution.”
