London will remember last year's terrorist attacks with the hashtag #Londonunited.

According to reports, the words will be beamed onto landmarks across the city where terrorist attacks took place in 2017.

Buildings in Westminster, London Bridge, Finsbury Park and Parsons Green will be lit up with the hashtag in memory of those killed.

The first memorial will be tomorrow, one year on from the attack on Westminster, in which four people died.
