BERLIN (Reuters) - German Chancellor Angela Merkel vowed on Friday to serve a full term in office through to the end of the current legislative period - which ends in 2021 - despite infighting in her ruling coalition over immigration policy.

Asked whether she had thought about resigning, Merkel told a news conference: “No, No. If I am in the middle of an important discussion, I must concentrate my efforts on it.”
