The European Union is considering taking disciplinary action against France over its treatment and expulsion of Roma migrants.
EU Justice Commissioner Viviane Reding described the actions of the French government as a 'disgrace'.
She added France had been duplicitous in how it had dealt with the European authorities over the issue.
Ms Reding said she believed proceedings should be brought against France in the coming weeks.
‘I am personally convinced that the commission will have no choice but to initiate infringement proceedings against France,’ Ms Reding said.
She rebuked the French government over a leaked memo which ‘openly contradicted’ assurances given by two ministers to the Commission that specific ethnic groups had not been targeted in France.
‘The role of the Commission as guardian of the treaties is made extremely difficult if we can no longer have confidence in the assurances given by two ministers in a formal meeting,’ Ms Reding said.
‘This is not a minor offence in a situation of this importance,’ she said.
Elsewhere, more than 200 Roma arrived in Bucharest after being expelled from France.
A total of 222 Roma landed at Bucharest's Aurel Vlaicu airport on two charter flights from Paris and the southern city of Marseille.
Many of the Roma, who received a cash payment to leave France, complained about poor economic prospects in Romania.
More than 1,000 Roma have been expelled since President Nicolas Sarkozy announced a clampdown in July.
