Sefton Central Labour MP Bill Esterson said he was honoured to attend the official re-opening of Aintree Davenhill Primary School last week.
Bill joined dignitaries, including the Countess of Wessex, at the special event.
Part of Aintree Davenhill was rebuilt and part refurbished as part of the last Labour Government's Primary Capital Programme.
Although the Tory-Lib Dem Government stopped the funding for the school, Labour-run Sefton Council provided the money required to complete the project.
Bill Esterson said: "I really was very honoured to attend the formal reopening ceremony of Aintree Davenhill Primary School.
"Aintree Davenhill is a fabulous community school. It now has fabulous buildings and facilities that the staff, pupils and community as a whole deserve.
"The pupils and staff put on a fantastic show for the opening. They should all be very proud."
Bill said he was delighted that Labour-run Sefton Council stepped in after the Tory-Lib Dem Government pulled the plug on the Aintree Davenhill project.
Bill said: "I remember speaking at the time to the staff and parents who were shocked that the funding had been cut by the government.
"Part of the project had been completed, but not all of it.
"Staff told me that the school was originally built in the 1950s from surplus aircraft hangers. The buildings were freezing in winter and boiling hot in summer. The school was long-overdue a rebuild.
"But now, the new buildings are fantastic. I was really impressed by the work which has been completed, a combination of new and refurbished buildings.
"As well as the new buildings they have some fantastic new classrooms and outside play areas.
"The old buildings really were not fit for teaching and learning, so it was really good that Sefton Council stepped in when this government let us all down and pulled the funding.
"I am always impressed by the dedication and commitment of the staff at Aintree Davenhill. It was also great to meet some of the children and to see their excitement at seeing their new school.
"Well done to staff, parents and governors for all their hard work.”
