Cornwall Council’s strategic planning committee will today decide the fate of a proposed £110 million retail park and Marks & Spencer store at Coyte Farm.
If approved the controversial plans - submitted by Metric Property and Mercian Developments - would see a major new retail park built on the outskirts of St Austell, incorporating Marks and Spencer, Next and Sainsbury's stores.
Those supporting the scheme say the development will create hundreds of jobs and boost the local economy.
However many traders fear the park is too big and would kill the town centre.
Dozens of people, both for and against the development, are expected to gather outside County Hall in Truro this morning in a final bid to sway councillors' votes ahead of the crunch meeting.
