Hundreds of people have signed a petition against plans for a supermarket on the site of a former recycling centre.
The Telegraph has previously reported that Lidl has applied to build a second store in Rushden.
They want a foodstore with new access, parking and associated landscaping on the site of the former recycling centre and council depot in Newton Road in the town.
However, a petition has been launched at the Londis store in Newton Road with more than 800 people signing it so far.
Concerns include an increase in traffic, safety concerns for those attending the school nearby, noise and competition for smaller independent businesses.
Londis store owner Mohan Momi said: “They will put the smaller businesses out of business.
“The biggest issue is this is my livelihood but you can’t object on the basis of competition.”
A spokesman for East Northamptonshire Council, which will consider the plans, confirmed that competition is not a material consideration when it comes to determining a planning application.
But Mr Momi said he also has other concerns, including traffic.
He said: “They built a bypass but what they are going to do is bring all the traffic back into the town.”
He believes the town has enough shops already, with big names including Tesco, Sainsbury’s, Asda, Waitrose and Lidl already having shops in the town, and said: “We don’t need any more shops.”
Assistant manager at the store Tina Cowland said: “It’s all the customers are talking about at the moment.
“Newton Road is a nightmare anyway, if there’s a crash on the A6 they divert all the traffic down here.
“They built the bypass to take the traffic away from Newton Road.
“It’s going to be absolute chaos.”
Tina added that the Lidl plans have not been displayed in the road yet, but a council spokesman said notices would be going up on Friday.
