LONDON, ENGLAND - JULY 18: Stickers are left on a 'Vote Leave' battle bus after it was re-branded outside the Houses of Parliament in Westminster by the environmental campaign group Greenpeace on July 18, 2016 in London, England. The bus which was used during the European Union (EU) referendum campaign and had the statement "We send the EU £350 million a week let's fund our NHS instead" along the side was today covered with thousands of questions for the new Prime Minister Theresa May and her government about what a 'Brexit' might mean for the environment.
