Swedish authorities have ordered the expulsion of a Chinese journalist, saying she could pose a serious threat to national security, a lawyer representing the woman said on Monday. The 57-year-old Chinese woman has lived in the country for almost 20 years and denied all the accusations, lawyer Leutrim Kadriu told Reuters. Kadriu did not name the woman or say whether she had already left. He said he could not go into details on the charges as they concerned national security and were officially confidential.
