The Trade and Industry Minister is to be questioned on alleged undercutting of private sector companies by Isle of Man Post.
Onchan MHK Peter Karran will ask David Cretney if he thinks it's wrong that a 'subsidised body' should compete against other parcel carriers who don't receive government support.
In a series of strongly worded questions he will also ask whether such allegedly 'unfair trading' is against the spirit of the Island's current agreement with Europe, which seeks to allow 'normal conditions of competition'.
Finally Mr Karran will ask if the minister is aware that management at Isle of Man Post are 'currently attempting to use their subsidised advantage to unfairly undercut local businesses that have been built up over many years.'
The questions have been tabled for Tuesday's sitting of the House of Keys.
