Disgraced former Queensland politician Scott Driscoll will spend the rest of this week behind bars on suicide watch, facing the prospect of years in prison.

Prosecutors asked for the former Liberal National Party MP, who has admitted 15 fraud charges, to be jailed for six years before his sentencing hearing was adjourned on Monday. His defence argued he should spend as little as six months behind bars.

The court heard Driscoll asked for Coles and Woolworths to give hundreds of thousands of dollars to a cash-strapped lobby group he headed to change his position on business trading hours.

In the conversation with a Coles representative in October 2012, Driscoll introduced himself as the Member for Redcliffe, which the Crown argued was "significant".
