Since the attacks in Manchester and London combatting terror has been a focus of the campaign.

Police numbers and authority for armed officers to shoot suspects have been debated.

The Conservatives have adopted a self styled strong on terror message however their manifesto simply states they will “maintain and develop our counter terrorism strategy to protect us from terrorism at home and abroad”.

Labour said it would “conduct a major review” of the Government’s anti terrorism strategy which is says has the “potential to drive a wedge between the authorities and and entire communities.”

The two largest UK parties have clashed on police since the latest terror attacks with the Tories accused of reducing police numbers over the last seven years. The Prime Minister has said she would consider new powers for the police to counter the terror threat. Her main target has been internet companies allowing pro terror material on their sites.

The Liberal Democrats said that there needs to be an effective security strategy but one that does not “unduly restrict personal liberty”

The party wants to “roll back state surveillance” and oppose Tory “attempts to undermine encryption”

The SNP calls for international co-operation in fighting terrorism as well as cyber-crime and organised crime.
