Photographs show the black car partly through a wall at the supermarket at Kingsmead Retail Park in Stafford. At least two fire engines have been spotted outside the store and an ambulance is thought to be present.
A cordon has been put in place around the scene of the collision.
The shop itself has had to close. A sign pinned to the entrance reads: “Due to a road traffic accident, the store is currently closed. Sorry for any inconvenience. Team Aldi.”
One worried shopper, who didn’t want to be named, said: “I didn’t see it happen as I was round the corner but I think I heard the sirens. I hope everyone is OK.”
A West Midlands Ambulance Service spokesman said paramedics were called to the scene just before 1.30pm to reports of a collision.
The spokeswoman added: “We sent two ambulances and a paramedic officer to the scene.
