It is the email that Christopher Pyne can't remember sending.

The National Times has obtained a hard copy of an email from the Liberal frontbencher asking for the contact details of the staffer at the centre of sexual harassment allegations against Speaker Peter Slipper.

An email from Christopher Pyne asking for the contact details of James Ashby.

Mr Pyne has twice this week been forced to alter his account of his dealings with James Hunter Ashby after he said at the weekend his contact with Mr Slipper's former staffer had been brief.

''I walk into the reception in the Speaker's office with Speaker's staffers there,'' Mr Pyne said on Sunday. ''I've said hello to all of them, so I passed the time of day with all of them.''
