Sefton Central Labour MP Bill Esterson is to meet the A Better Crosby campaign group this week to discuss his recent meeting with Sainsbury's in Parliament.
Crosby's MP got assurances from supermarket chiefs that they were committed to the Village site during the meeting.
Sainsbury's head of planning Sue Willcox and zone director for the North of England Dean Clegg also assured Bill that plans would be drawn up with full consultation with the community.
Bill said: "My meeting with Dean Clegg and Sue Wilcox was very interesting. They both listened to all of the concerns which residents and the A Better Crosby group had made to me.
"From the outset I got their assurances that they were committed to the Crosby Village site.
"And from that point we then discussed how they will redraw their plans for Crosby. But before they submit anything, they assured me that they will consult with the community and listen to all of the viewpoints before making a final decision.
"That is why it is crucial that the community is involved in the process from very early on."
Bill said he got the agreement from Sainsbury's for an early meeting with A Better Crosby and other community stakeholders.
Bill said: "Both Sue and Dean told me they would make arrangements for a meeting with members of the community in the next few months. I will be pushing them to fix a date for the meeting so we can get the ball rolling.
"Everyone agrees that we need investment in Crosby Village.
"We want a thriving town centre of numerous businesses with Sainsbury's playing a large part in that.
"It is in the interests of Sainsbury's to get the community on their side, the only way to do that is by working with the community.
"This is what I will be discussing with A Better Crosby and what we as a community need to do to make sure that the interests of the community are best served."
