In 2008 Tesco bought land in Machynlleth and wants to open a new 27,000 sq ft supermarket.
From 2008-2010 Keep Mach Special campaign group opposed the plans and finally, on 22nd June 2010 the Welsh Assembly ruled that Tesco's planning application for a store in Machynlleth should be refused on safety grounds. The Welsh Assembly Government directed Powys County Council to refuse the plans as it would lead to more road accidents.
In 2008 local residents and the Chamber of Commerce were concerned about the Tesco plans, especially as the town already has a Co-op and Spar and Harry Tuffins, has recently opened a store.Around 250 people attended a public meeting to discuss the plans in October 2008.
January 2010 -a decision by Councillors on whether to allow an extension to be built at the Co-op store in Machynlleth was put on hold because of the weather. Originally it was intended to discuss the Co-op plan and the Tesco planning application at the same meeting, but planners decided to defer the Tesco item after the Welsh Assembly Government said it wanted more time to consider the proposal.
