Scottish Labour will call for equality and fairness in society with an attack on "tax-dodging" millionaires whose neighbours are living on food parcels.
The party's deputy leader Anas Sarwar said companies like online retailer Amazon do not pay their fair share in tax, and criticised the UK and Scottish Governments for continuing to hand them development grants.
Mr Sarwar will name Amazon in a speech on equality and fairness in Glasgow`s Gorbals area on Monday morning.
In advance extracts of the speech, he said: "One mile away from here millionaires are getting handed a tax cut. A mile in the other direction people getting handed a food parcel. People living in the same world, but living in a parallel universe.
"When today people are struggling to feed themselves and their families, are worried about paying their rent or mortgage, are seeing their wages squeezed and their hours cut they see large multinational, multimillion pound companies making huge profits but paying not a penny in tax."
He added: "That is not just economic immorality on the part of the company, it is political immorality on the part of Government for rewarding such behaviour.
"That is why every Government should rightly check and ensure any company that receives a Government grant pays their fair share of tax and is not tax-dodging. And we are proud of the fact that it was a Labour council that first introduced the Living Wage in the public sector.
"We must now promote the Living Wage throughout the public sector and into the private sector through Government and Local Authority procurement."
An SNP spokesman said: "It is time for Labour to be straight with the people of Scotland on which popular services they want their Cuts Commission to axe. Anas Sarwar has said he doesn't think there is any point in universal benefits like personal care for the elderly because some people do not live long enough to benefit, or free higher education because some younger people don't go to university.
"These policies, fully supported by the SNP Government, are cornerstones of a fair Scotland. But Mr Sarwar needs to come clean and answer a simple question - are these things that Labour's Cuts Commission wants to scrap?"
