Angela Merkel has denied claims made in a new book that she played a senior role in the East German communist youth movement.
The allegations in the book relate to a period when the German Chancellor studied for her doctorate and worked as a researcher at the Academy of Sciences in east Berlin.
The book, The First Life of Angela M, written by two German journalists, claims that in 1981 - when she was in her late twenties - she became "agitprop" secretary of the academy. This would have made her responsible for promoting communist ideology.
Merkel said she had never hidden anything about her life in East Germany, although she acknowledged that some things may emerge "because no one has ever asked me about them".
"What is important to me is that I have never hidden anything," she said after attending the screening of an old East German film in Berlin.
