The campaign pressuring Premier League clubs to install disability facilities and improve access to stadia has gained significant weight after the Equality and Human Rights Commission (EHRC) announced its support.
Campaigners have criticised clubs for making only limited progress on improving access for disabled fans, in spite of the August deadline for toilet facility improvements.
According to EHRC, 13 out of the 20 teams are not providing the required number of wheelchair spaces. But the Premier League insisted its clubs were working hard to improve facilities, according to a report by the BBC.
Following a BBC report in 2014 which found that 17 of 20 clubs did not provide enough wheelchair spaces, clubs set self-imposed deadline to meet standards by August 2017.
EHRC chair David Isaac claimed it would investigate clubs who had did not meet the minimum requirements or publish an action plan for improvement.
“The end of the season is fast approaching and time is running out for clubs,” he told the BBC.
“The information we received from some clubs was of an appalling standard, with data missing and with insufficient detail. What is clear is that very few clubs are doing the minimum to meet the needs of disabled supporters.
“The Premier League itself does not escape blame. They need to make the concerns of disabled fans a priority and start enforcing their own rule book. We will be meeting individual clubs and asking them to explain themselves and tell us what their plans are.”
According to the EHRC, the following clubs have not met requirements in wheelchair spaces: Arsenal, Burnley, Chelsea, Crystal Palace, Everton, Hull, Liverpool, Man Utd, Stoke, Sunderland, Tottenham, Watford, West Brom.
Meanwhile, the EHRC said the following clubs have not met requirements in toilets: Bournemouth, Burnley, Chelsea, Crystal Palace, Everton, Hull, Middlesbrough, Stoke, Sunderland, Swansea, Tottenham, Watford, West Brom.
