ATHENS (Reuters) - Greece has threatened not to sign off on the final conclusions of an EU summit on migration and Britain's membership, holding out for assurances EU states will not shut borders over the migrant crisis, government officials said on Friday.
"We can't agree unless there is a clear statement in the conclusions that there won't be any unilateral (migrant) action until the next summit. No borders should close until then," one of the officials told Reuters.
The official said Greek Prime Minister Alexis Tsipras has been given assurances by Germany and France that they would support his position. Other countries have expressed differences, however.
