Angry protestors threw smoke bombs at the entrance of Shoreditch House, where the UK launch of Creative France – Business France’s new campaign to promote French creativity – was taking place.
Dozens of campaigners clad in black and wearing masks held on the banners bearing slogans in solidarity for the evicted refugees.
CEO of Business France Muriel Penicaud was reportedly attending the event inside the building in central London at the time the demonstrators gathered.
Police were forced to blockade the entrance as protestors handed out leaflets criticising the French Government’s decision to move migrants on.
A Metropolitan Police spokesman said: “Police were called to Ebor Street, E1, to reports of a protest taking place at approximately 6.50pm.
“Officers are currently on scene. An appropriate policing plan is in place.”
French authorities gave refugees in the Calais jungle until 8pm on Tuesday to clear out of the shanty town before the bulldozers moved in.
The jungle residents were forced to move into alternative accommodation provided by the French government or head to another camp.
More than 1,000 migrants were evicted from the south part of the Calais jungle before French authorities start to demolish the shanty town on Wednesday.
The decision to demolish the migrant camp was deferred by a French court earlier today in response to an appeal from residents and activists.
Judge Valerie Quemener of the administrative court in the regional capital Lille, said: “The decision will not be taken today.
Belgium, meanwhile, announced it was stepping up random checks at its nearby border in anticipation of the clearance of the so-called “jungle” near the northern French port.
