West Lancashire MP Rosie Cooper has given her backing to Skelmersdale postal workers over their refusal to deliver The Sun’s World Cup promotional edition to homes in the town.
Mrs Cooper said she has contacted both the Chief Executive of the Royal Mail and the newspaper's Editor over the issue.
It took 22 years for the families to secure the truth, now in the 25th anniversary year the families and survivors are attending the inquest hearings in the fight for justice.
"I hope the Royal Mail will change its stance and show some integrity and most of all show some respect for the people of Skelmersdale and across West Lancashire who have lived with the lies and injustice promulgated by this newspaper in one of the darkest episodes in recent British history.”
A number of postal workers in Skelmersdale in Lancashire have threatened to walk out if they are forced to deliver free copies of The Sun later this week.
The Sun, which has planned a nationwide drop of its free World Cup-themed promotion, has agreed not to send out copies in Liverpool, where there is still widespread anger over the way it reported the 1989 Hillsborough disaster.
However, the tabloid newspaper is still set to go out in some areas of Merseyside, because they do not have Merseyside postcodes.
The Royal Mail said any concerns would be handled "with fairness and dignity".
