Hundreds gathered in London to mark the tenth anniversary of the Brexit referendum. Demonstrators are calling for the UK to rejoin the European Union, arguing that the economic benefits promised following the 2016 vote have not materialized. Protesters voiced concerns over unfulfilled promises of prosperity linked to leaving the EU. The demonstration involved a march across Westminster Bridge, passing by the iconic Big Ben. The 2016 referendum saw the UK vote to leave the EU after decades of membership. Organizers framed the protest as a demand for a reversal of the Brexit decision and a return to closer ties with Europe.
