The attacks on London Bridge and Borough Market mark the second time the General Election has been disrupted by an act of terrorism.

It comes less than two weeks after the parties suspended campaigning following the Manchester attack in which suicide bomber Salman Abedi killed 22 people attending an Ariana Grande concert.

There was no immediate announcement whether there would be a further suspension following the latest incident - which came just days before voters are due go to the polls on June 8.
