“It will draw large traffic into the most densely populated parts of the UK.
All I see I self-interest in this tunnel, all I see is harm, but to some it’s big money and to (London mayor Sadiq) Khan it probably is his pension.
As the activists made their way through London’s streets, they were escorted by City of London Police officers.
