A Danish man has pleaded not guilty to killing his Nigerian wife and daughter at their home in the commercial capital Lagos.

Peter Nielsen is accused of killing his wife, a singer known as Alizee, and their three-year-old daughter, in April in the upscale neighbourhood of Banana Island.

Prosecutors say his wife suffered head injuries while the young girl was found poisoned.

The woman's relatives and campaigners against domestic violence organised protests before Mr Nielsen's previous court appearances.

The case, which has been covered extensively in the Nigerian media, has been adjourned until October.
