London: Protesters waving banners against voters' decision to leave the European Union (EU) marched through central London on Saturday. The March For Europe demonstration, organised on social media by comedian Mark Thomas, started at Hyde park. The protesters made its way to the Parliament Square, where there were speeches, Xinhua cited Sky News as saying. Banners and placards showing slogans such as "No Brex Please, We're British", "Europe Innit", "I wanna be deep inside EU", "All EU Need is Love", and "Science Needs EU" could be seen during the demonstration. Outgoing Prime Minister David Cameron has said the referendum result, where about 52 per cent voted to leave the EU, would be respected and the government had begun laying the groundwork for the complicated Brexit negotiations. From the stage in Parliament Square, Labor politician Lord Cashman told the crowd that British people "need to uphold the values of democracy and inclusiveness which are at the heart of the EU and this country," according to the Sky News.
