LONDON, United Kingdom – A throng of nearly 200 pro-migrant rioters descended on London’s St. Pancras mainline station tonight – the terminal that connects the UK’s capital city with mainland Europe – to demand “no borders” and “no nations”. The scenes, brought to you exclusively by Breitbart London, shows violent clashes between police and protesters, with London’s cops looking woefully unprepared. Calais Migrant Solidarity, an umbrella group of hard-left protesters, descended on the station after attending an “Anarchist Book Fair” – seemingly undeterred by the hypocrisy of anarchist philosophy wanting less government intervention, while most of the protesters in attendance are familiar faces from left-wing marches demanding more government interference in the marketplace, and in civil society. And what they experienced tonight was just that – government in action – as they came head to head with London’s police. But in this case, it seems they were successful, breaking through police lines, and hurling smoke bombs into one of the busiest railway stations in the country, endangering themselves, police, members of the public and tourists with their demands to welcome unlimited numbers of “refugees” into Britain.
