Former Premier League ref Mark Halsey has claimed he was told by the refereeing body to say he had not seen incidents in matches.

Premier League rules state no retrospective action can be taken if the incident was seen by the official at the time.

But Halsey, in conversation on Twitter, made the shocking claim he had been told by PGMOL - the organising body for elite referees in England - to say he hadn't seen incidents that he had actually witnessed.

"I have been in that situation," he wrote, "when I have seen an incident and been told to say I haven't seen it."

When quizzed further on who had pressurised him, Halsey revealed: "To be fair to the FA... it's not them.

"It comes from within the PGMOL."

The PGMOL was formed in 2001 to improve refereeing standards and provides officials for across the Premier League, Football League and FA competitions, receiving funding from all three bodies.

Gary Neville, the former Manchester United defender and Valencia boss, tweeted: "Is that not corrupt?

"Mark, I'd like to know who told you to say that!

"@FA and @premierleague think you have a major issue on your hands!!

"I've spoken with Mark. Verified the statement. Huge problem!!!"

The PGMO told Mirror Sport in a statement:

"Match officials submit their reports, including critical incidents, directly to the FA. Match officials ensure that their reports are a full and accurate description of the incident. There is no pressure from the PGMO to include or omit anything."
