Sefton Central Labour MP Bill Esterson said one of his main priorities for Crosby is to "get things going in the Village".
Speaking as he stepped up his campaign to get Sainsbury's back around the table, the MP said it is vital that things get moving quickly.
Sainsbury's broke off their discussions on the future of Crosby Village last year.
Bill said: "The important thing is that we get Sainsbury's back to the table and we get a development in Crosby that has the support of the local community.
"I have been lobbying Sainsbury's in the past two years to do this and I will continue to work with Sainsbury's and local groups and residents to improve the state of Crosby town centre.
"It is vital that this happens as quickly as possible.
"I am disappointed that Sainsbury's did break off their discussions last year but what is important is what happens now and in the future. That's why I am pressing Sainsbury's to agree to a proposal that is the right scale for the town centre, that supports existing traders and new businesses so that the people who live and shop in Crosby benefit as soon as possible."
Bill has been invited into the Crosby store to see for himself the improvements have recently been made. The MP will use the opportunity to raise the wider issue of Crosby Village.
Bill said: "I have written to Sainsbury's in the last few weeks and I am waiting to hear back from them.
"They have invited me into the current store to have a look at the improvements they have made to the existing store and I will be again taking up with them that they need to make real their improvements for Crosby Village in consultation with the community so that we end up with a town centre that is beneficial to the community.
"As a responsible business, I see that as Sainsbury's duty to the community given the money they make from the people of Crosby."
Bill said it was his responsibility as the local MP to campaign for the best interests of the community.
Bill said: "My job is to lobby the people who are in a position to make a difference.
"The private sector is where the money will come from for any improvements to Crosby Village and it is the private sector who I am speaking to - that includes Sainsbury's.
"As the local MP, I have a responsibility to the community. I talk to people here all the time to look at ideas to persuade Sainsbury's to put the money in.
"I will continue to listen to the people of Crosby. Hear what they want for their community and campaign on their behalf so that we can start the process of regenerating the Village for the good of the whole community."
