Scott Morrison's office says it has found no correspondence from Daryl Maguire

Prime minister says police should investigate all issues associated with government's Leppington Triangle land purchase

Scott Morrison's office says preliminary searches have not located any correspondence from the disgraced New South Wales MP Daryl Maguire during Morrison's time in the immigration portfolio, or while he has been prime minister.

During a hearing last week in the NSW independent commission against corruption, Maguire admitted to receiving thousands of dollars in cash to his parliamentary office from a former business associate, Maggie Wang, in relation to a cash-for-visa" scheme the two established.
