Liberal candidate for Indi Sophie Mirabella has angered her party by suggesting she is the victim of internal leaks aimed at destabilising her bid to unseat independent Cathy McGowan.

Ms Mirabella, a former Coalition frontbencher who lost the sprawling Victorian seat at the 2013 election, was responding to reports that she was "cooked" in the electorate.

"It's better not to say," she told the ABC's 7.30 program when asked where the reports had emanated from.
