As many as twenty two people have been killed and dozens injured following a suspected terrorist attack in Manchester.
An explosion rocked the Manchester Arena at 22:35 on Monday evening following a concert by US singer Ariana Grande.
More than 50 people were injured during the incident, with many in hospital over night with serious injuries.
The Conservatives, Labour, SNP and Liberal Democrats have all confirmed that campaigning in the general election will been suspended on Tuesday.
Prime minister Theresa May said: “We are working to establish the full details of what happened in Manchester.
“All our thoughts are with the victims and the families of those who have been affected.”
May will chair a meeting of the emergency Cobra committee at around 09:00 this morning.
British Transport Police said the explosion was in the foyer of the arena.
The area connects with Victoria train and tram station, a major hub on the northern edge of the city centre.
Shortly after the blast the station was closed and all trains cancelled.
The explosion occurred shortly after Grande left the stage at the arena.
It is the largest indoor venue in the city with a concert capacity of around 18,000.
