Star Liberal candidate Warren Mundine has pledged to divest all his business interests before the election - including a company that last year received a $5 million government grant - to ensure he does not fall foul of the Constitution's notorious section 44.

Grant records show Real Futures - a vocational training company of which Mr Mundine is the chairman and part-owner - initially received a $4.5 million Commonwealth grant in February 2018 after a non-competitive selection process.

The grant increased to $5 million on August 27, just days after Scott Morrison became Prime Minister. It covers a period from February 2018 to June 2020.

Mr Mundine was neither a candidate nor a member of the Liberal Party when the grant was awarded, and there is no suggestion of wrongdoing or malpractice by the government.
