Tens of thousands of people are expected to attend a special vigil outside Liverpool's St George's Hall following the Hillsborough inquests verdict, which absolved the 96 people who died during the tragedy of any wrongdoing and ruled they were all unlawfully killed.

Following a 27-year battle for families and supporters of the victims to have the original accidental death verdicts quashed, a jury ruled all 96 Liverpool fans who died at Sheffield Wednesday's stadium during the 1989 FA Cup final did so as a result of "gross negligence" by police, as well as ambulance services and stadium engineers.

A special commemoration event, led by Mayor of Liverpool Joe Anderson, will now take place in the city centre. It will involve speeches by the families of the 96 victims as well as tributes and "moments of reflection" looking back at the fight for justice.

Following the historic inquest verdict, 96 lanterns were placed at the steps of the hall alongside a huge banner with the words "justice" and "truth". Today, (27 April) flags will be flown at half-mast on all civic buildings and several other of Liverpool's iconic buildings including the Town Hall, Municipal Building and the Royal Court will be lit up in red to show solidarity for the 96 Liverpool supporters and their families. The bells at Liverpool Town Hall and Municipal Building will also be rung 96 times at 3.06pm – the exact time at which the FA Cup match was stopped.

The names and ages of all those who died at the tragedy will also displayed on large screens, and proceedings will conclude with the Sense of Sound choir performing You'll Never Walk Alone.

Anderson said: "[This] commemorative event at St George's Hall is an opportunity for the city to come together with the families and campaigners and show the world the overwhelming spirit of comradeship and solidarity that exists in this city.

"So many people have been touched by their struggle over nearly three decades. They are an example to everyone who seeks out truth and justice and tomorrow's event is a chance for the city to say 'thank you' to them and to remember the lives of their loved ones."

The event will be broadcast live on the LFCTV channel, available for free to those with a Sky box (on channel 429) in the United Kingdom and Ireland, or any Virgin Media subscription (on channel 544) in the United Kingdom only.
