Ten years on from the 7/7 terrorist attacks in London, prime minister David Cameron and London mayor Boris Johnson this week visited the Hyde Park memorial to those killed in the attacks, consisting of a steel column for each victim, 52 in total.
Cameron and Johnson walked alongside one another through the array of steel columns, emerging at the commemorative plaque at the end of the path that leads through the memorial.
Here they crouched to lay floral wreaths by the plaque, before turning and walking away in unison.
Further dignitaries followed the route through the forest of steel pillars, again in pairs, and including representatives of London’s transport network and of the city’s law enforcement.
The two-by-two wreath-laying was symbolic of the Walk Together theme that has surrounded this tenth anniversary on social networks.
Londoners commemorated the anniversary in a show of solidarity, departing the Tube, train or bus a stop early and walking the remainder of their morning commute, often in pairs or groups.
The steel pillars in Hyde Park, along with the other memorials around the city, are a similar emblem of unity and strength, as well as an enduring reminder of those who were killed or injured in the attacks.
