A note has been pinned to Ukip's campaign office in South London that chastises the party for imposing "fear, hatred and prejudice" on the area, according to one Twitter user.
"To the people of this shop and to those that enter here... Ukip. I am with my 13 year old son walking to get something to eat and I see your hordings and advertising and I feel nothing but shame and absolute indignation that you impose your fear, hatred and prejudice on our communities.
"You should be driven back into the hole where you are from just so you know we are all beautiful people and your politics, your acism will never win. Love compassion and tolerance will defeat you...."
