Read the text and determine if the sentence is true:

Photographs published by the Investigate magazine and the newspaper Sunday Star Times has shown the Prime Minister of New Zealand Helen Clark's husband, Peter Davis, being hugged and kissed by openly gay Auckland GP (General Practitioner) Dr. Ian Scott on election night 2005. The editor of Investigate, Ian Wishart, stated that at no time has Investigate ever suggested Davis is gay. Wishart said that he has "Been targeting Mr Davis for months and has appealed for readers to send him details of his private life. [My] article makes no homosexual inferences and is merely an attempt to background Davis ahead of reports to follow."

Sentence: Ian Wishart has ulterior motives.
