Sefton Central Labour MP Bill Esterson said that he will continue to fight Tory plans to redraw constituency boundaries which sees Formby split in two.
Bill said while Nick Clegg had announced he was consigning the plans to the Parliamentary rubbish pile after realising his party would lose eight seats, you couldn't trust the Lib Dems to honour their pledges - so the campaign was still on.
Under the Tories' proposals, Sefton Central would become the new constituency of Crosby and Maghull. The new constituency would include the wards of Ravenmeols, Molyneux, Sudell, Park, Manor and Blundellsands, with the inclusion of Church and Victoria wards (both are currently in Bootle constituency).
The Formby ward of Harington would be cut off and placed in Southport constituency.
Bill said: "The Tories are determined to continue to push for these boundary changes which split Formby in two.
"Under their plans, Harington is split away from Ravenmeols are placed into Southport. This would be damaging for the people of Formby whose interests would not be best served
"Week in and week out I knock on doors in this community, which includes Harington and Ravenmeols wards, to listen to Formby people's concerns and the viewpoints of people who live here to feed back to Parliament and also to act upon locally.
"As MP for the town I see that as one of my primary responsibilities.
"Would the concerns of Harington Ward still be served by an MP in Southport who would see it as a distant relation of his constituency?
"As I have said all along, I oppose these plans.
"The community of Formby is one of the most historic communities in the region and it is simply bizarre to think that it could be arbitrarily split up by these boundary changes.
"Formby needs to remain together and that is what I am continuing to campaign for."
Bill said the plans had been drawn up with political motives and not in the interests of the communities.
Bill said: "All along the Labour Party have been against these proposals because they are not in the interests of the electorate.
"While the Tories have been busy gerrymandering the boundaries in their own interests, slashing the number of MPs, they have increased the number of unelected Lords by a lot more.
"Not only is this undemocratic, it sees the representation of those who most need it reduced. At a time when areas like ours are being devastated by the Tory-Lib Dem Government's slash and burn policies, it is areas like ours which are having their Parliamentary representation watered down, while the leafy shires would keep their MPs.
"It is nothing more than gerrymandering.
"We all remember what happened under Thatcher in the '80s and just what damage the Tories did to this part of the world. How whole families were thrown on the rubbish heap as unemployment rocketed.
"Well now the Tories are doing the same, but this time the Liberal Democrats are helping them do it.
"I will be voting against the proposals as I want to continue to represent the whole of Formby. Local Tories need to persuade their MPs to do the same otherwise their claim that they don't want to split Formby is meaningless. It is the Tories who want to split Formby. I will fight their plans."
