The government yesterday announced a United Kingdom lockdown in which people should stay at home and all non-essential shops should close.
Fellow Labour MP Bill Esterson tweeted "But not Sports Direct" above a list of businesses allowed to stay open under the new measures, while Nottingham South MP Lilian Greenwood encouraged her constituents to "show Mike Ashley what we think of this profiteering".
Sports Direct said it will remain shut for the time being after Mr Johnson ordered the immediate closure of non-essential stores, but B&Q is preparing to reopen to provide "only essential products" to customers and traders after being allowed to stay open.
The Wansbeck MP added that selling sports equipment "is not an essential service", while Alyn and Deeside MP Mark Tami said Sports Direct staying open could potentially be "putting vulnerable people at risk".

The cost of a 12kg kettle bell by Everlast, which is owned by Sports Direct's parent company Frasers Group, is now £39.99, up from £29.99.
After heavy criticism from unions and politicians alike, the discount retailer was forced to clarify its position in a second email to its staff, saying its 700 stores nationwide would only open if given permission from the United Kingdom government to do so.
"And I understand they will not be remaining open".
"We feel disrespected by Mike Ashley's decisions to try and keep the company trading".
The retailer said it is contacting the Government "at all levels" in an attempt to get confirmation from the prime minister.More news: Coronavirus: Sadiq Khan warns 'stop Tube travel or more will die'
"Against the backdrop of the closure of gyms the demand for these types of products has increased exponentially as the population looks to maintain a healthy lifestyle".
He added the store is, "uniquely well-placed to help keep the United Kingdom as fit and healthy as possible".
It said it will not now open "until we are given the go-ahead by the government".
