Parents, their children and young people have taken to the streets to demand the Government acts to end a "national crisis" in special educational needs and disabilities (SEND) funding.
Campaign group SEND National Crisis will also deliver a petition with more than 12,000 signatures to Downing Street.
In the North West parents gathered in Manchester and Liverpool.
According to the National Education Union (NEU), special needs provision in England has lost out on £1.2 billion since 2015.
It says funding granted to local authorities has failed to keep pace demand for SEND provision.
The number of children and young people with an education health and care plan has increased by 33% since 2015.
