Sefton Central Labour MP Bill Esterson and members of Maghull Labour Action Team met with Wetherspoons on Friday to discuss the company's plans for the Everest pub.
Bill, together with Maghull Labour Action Team's Cllr Patrick McKinley, Lynn Gatherer and Steve Kermode, and a delegation of local residents met with representatives of the national pub chain at the MP's Maghull office.
Concerns were also raised by residents who attended the meeting about how long it has taken for the pub chain to speak to residents and about the fact that work has already started before discussions have taken place with the local community.
Amongst the Wetherspoons representatives were the company's area manager.
Bill said the meeting had been full and frank with Wetherspoons giving assurances that they would tackle residents' concerns.
Bill said: "The meeting between Maghull Labour Action Team, the local residents and the Wetherspoons representatives was very constructive.
"We quizzed the Wetherspoons representatives for more than one hour and it was particularly useful to have some of the concerned residents there to directly put their concerns to the company.
"Some of the main issues of concern were the issues of parking, noise, changes to opening hours, fears over large numbers of people getting drunk and going to and from the pub and the scale of the beer garden.
"The Wetherspoons representatives, which included the area manager, assured us that they would tackle the concerns as part of their plans for the site.
"This is something which the Maghull Labour Action Team and I will ensure happens."
Maghull Labour Action Team's Lynn Gatherer said she had already had conversations with lots of residents concerning the pub.
Lynn said: "Obviously, the Everest is one of the main issues on the doorstep, particularly in the area immediately surrounding the pub.
"I live very close the site myself, so I know only too well the main issues of concern.
"From the start, Maghull Labour Action Team has ensured that residents have a say and that Wetherspoons have been made aware of the concerns.
"That's why we organised the meeting with Wetherspoons, its why residents were invited to attend with us and its why we are organising ongoing public meetings to ensure that everyone is kept fully informed and the company acts on the concerns raise with them."
Sudell Ward's Labour Councillor Patrick McKinley said the Maghull Labour Action Team would now push to ensure that Wetherspoons kept its promises to tackle the concerns regarding the plans.
Cllr McKinley said: "Wetherspoons' representatives gave us their promises that they would directly tackle the concerns which were raised during last Friday's meeting.
"This included revisiting opening hours which means people will be off the site by midnight, deliveries will be made in consideration with the community and outside of the school-run peak hours and they have also assured us that they will reconsider their plans to reduce the number of parking spaces.
"Wetherspoons are now well aware that they should have better consulted with the community before submitting their plans. This has led to a sense of distrust in the community.
"Our MP, Maghull Labour Action Team and I will fight to ensure that residents are heard and that this pub is to the benefit of the local community and not to its detriment."
