Turnbull could be forced to front Senate inquiry to explain $444m reef grant

Labor and Greens say former PM could 'put to bed' why government money was given to private charity

Malcolm Turnbull could be compelled to appear at a Senate inquiry examining the government's $443.8m grant to the Great Barrier Reef Foundation under a Labor and Greens push.

Although MPs cannot be compelled to answer questions in Senate committees, Turnbull's decision to resign as member for Wentworth on Friday means he could be forced to front the inquiry examining the grant.
