Trade unionists and campaigners demonstrated across Britain to mark Workers’ Memorial Day on Tuesday. This highlights the level of deaths on construction sites.
Around 200 people took part in the London demonstration.
The march halted outside the Riverbank House site where a young worker was recently killed. The main contractor on the site, McAlpine, was one of the biggest users of the blacklist, which meant that workers who built unions or raised health and safety concerns were denied work.
