A photographer whose snap of “anti-homeless spikes” outside a London Tesco launched a mass campaign announced plans yesterday for a protest at the site. 

Journalist Joshua Preston shone a light on sharp metal studs outside Tesco stores designed to stop homeless people from bedding down. 

Thousands of people shared his picture on social media amid a wave of anger over the previously unnoticed attack on Britain’s poorest. 

Now Mr Preston has urged them to join him at a People’s Assembly protest outside the Tesco Metro store in Piccadilly on June 21. 

Over 600 people have already signed up to rally at the store before joining thousands more anti-austerity activists on the movement’s huge march on Parliament Square. 

Mr Preston said: “We want homes not spikes, a permanent solution — and we will show Tesco that its decision to victimise the homeless is shameful, in any society. 

“These spikes must be removed immediately and we will continue to mass outside the store until they get rid of them.”

The protest was called only hours after the spikes at the London store were covered in concrete overnight by activists dressed as workmen.
