A man is due to appear in court today charged with the murder of Wanganui toddler Karl Perigo-Check.

Wanganui freezing worker David Bourke will tomorrow be charged with murdering his brother, police say.

Michael Laws is embroiled in fresh controversy after an email exchange over the 'h' in Wanganui went viral.

Wanganui's mayor said Pita Sharples did not understand "any culture that is not Maori", after the Maori Party co-leader called for Wanganui residents to accept its new name.

Iwi say Laws approached them about a compromise on putting an "h" into the city's name, but was told unequivocally there was none.
