National campaigning in the General Election has been suspended in the wake of the terror attack at London Bridge.
A senior Conservative spokesman said national events were being suspended and a decision on further campaigning would be taken later in the day.
It is the second time the campaign for the June 8 poll has been interrupted by atrocities, following a three day pause after the suicide bomb attack in Manchester.
Labour leader Jeremy Corbyn said his party would also be suspending national campaigning until the evening, after consultation with other parties.
The final cordon has been lifted in London Bridge after the attack which killed eight people.
A survivor of the London Bridge atrocity has said she feels lucky to be alive after her throat was cut in the attack.
Police said the fake explosive belts worn by the three London Bridge attackers were designed to cause "maximum fear".
