LONDON, MARCH 23 - More than a million people took to the streets in London in today's big anti-Brexit march to invoke a second referendum. The promoters of the 'People's Vote' platform state this, speaking of an "extraordinary" participation. The figure, not corroborated by independent sources, goes beyond that indicated in the previous similar event that took place in the heart of the British capital last October with an estimated estimate of 700,000 people.
