Lee Rowley feels the lack of consultation across the town on the matter has been 'unacceptable'.
Bus users in Killamarsh will find it more difficult to get to Chesterfield and Sheffield from next month.
It's as the 71 bus service is to be discontinued from the 1st September.
North East Derbyshire's MP Lee Rowley says there's been zero consultation with residents in the town;
"These services might not be used by a large number of people, but they're very important the people who do use them.
"Residents don't get up at 4am or 5am to use these buses for no reason; they do it to get to work.
"You have to work with people, and South Yorkshire Passenger Transport Executive haven't been doing that.
"As the local MP for Killamarsh, I want to stand up and say that this is unacceptable."
In response, South Yorkshire Passenger Transport Executive told us;
"From 1 September 2019, changes will affect local bus services as fewer passengers, increased running costs and reduced transport funding continue to put pressure on South Yorkshire’s bus network.
As part of these changes, South Yorkshire Passenger Transport Executive (SYPTE) has had to make the difficult decision not to renew its funding of early-morning, late-night and Sunday journeys on the 71 bus which serves Killamarsh. However, service 50 provides an alternative for the local community.
