“There’s still a lot of people who are so interested in the Hillsborough tragedy, which is good.

“I’ve already had an email from someone asking if he could have 50 tickets.

“It’s a shame we have to refuse people, but our main priority is safety, not numbers.”

The Hillsborough Justice Campaign, however, voiced their disapproval with the move.

Spokesewoman Sheila Coleman said: “We do not like the idea of tickets. It’s not a football match, but a memorial service which should be inclusive, not exclusive.

“The ground should be open to all those who wish to pay their respects.”

Last April’s service saw Secretary of State for Culture, Media and Sport Andy Burnham temporarily halt his speech as passionate chants of “Justice For The 96” rang down from The Kop.

LFC stadium manager Ged Poynton added: “We want everyone who wishes to attend the service to be able to do so, but in the safest possible environment.

“All tickets will be issued on an unreserved basis and will not be available on the day of the service.”

Tickets can be obtained from the club, the Liverpool FC stores in Williamson Square and Liverpool One, with a maximum of six per application.
