Wembley Academy finally opened its doors to pupils on Tuesday morning after nearly two years of debate, controversy and vehement protests.
About 20 primary school children moved into a block of temporary classrooms on the former Bridge Road recreation ground - but there was no fanfare, no grand ceremony and no ribbon-cutting.
A further 40 reception pupils will have moved in by tomorrow (Friday), despite the fact that building work is still taking place on the exterior of the buildings.
Campaigners have hit out at Brent Council, accusing it of subterfuge for failing to make the opening public knowledge, and claiming the buildings are in "a state."
Jean and Hank Roberts, from Wembley Park Action Group (WPAG), were key figures in the anti-academy campaign.
They said: "It says a lot about the subterfuge of Brent Council over the academy that the temporary class rooms have opened and no-one knew.
"They have kept this very quiet. You would expect them to be trumpeting the opening around, but they have not made it public knowledge."
Councillor Bob Wharton, responsible for children and families, refuted the claims, saying he was astonished by the attitude of the protesters.
He said: "What were they planning to do? Come down and have a demonstration while four-year-old children start their first day at school?
"There was absolutely no secrecy, and I am delighted the school has finally opened. It will be a valuable addition to the borough as we are so tight on school places."
The council claims a formal opening will take place in November.
Over the past 18 months there have been three illegal occupations of the academy site as demonstrators attempted to scupper the council's plans for the new school.
They believe a new school is needed in the south of the borough, where there is a greater need for places, and say the academy model is indirect privatisation of state education.
They are also unhappy about the loss of public sports pitches on the recreation ground, and believe the academy will bring traffic congestion to the area.
Last Friday, Mr Roberts and members of WPAG picketed the headquarters of education charity ARK, which is sponsoring the academy.
Mr Roberts said: "The temporary classrooms at Wembley Park are already a month late and are still not ready despite their repeated promises they would be.
"We intend to carry the fight forward to forthrightly oppose the planning application against the permanent academy." * What do you think? Have your say at www.harrowobserver.co.uk
