The European Parliament's Secretary General, Klaus Welle, has urged Euro politicians to speak more slowly and to stick to their native language instead of using English. This is to help the hundreds of interpreters who work at the institution. Mr Welle said many interpreters were encountering difficulties doing their job. He said: "It's extremely important that people do not speak too fast." He asked politicians not to use English if it was not their native language as this complicates things for the translators. He added: "It's also extremely important for interpreters that people speak their own language. If the politicians speak a foreign language, the quality of interpretation goes down."
