LONDON — A memorial to Karl Marx at a cemetery in North London has been defaced for the second time in less than two weeks.

This time, vandals splashed the monument to the 19th-century political philosopher in Highgate Cemetery — which is listed among British structures with exceptional historical interest — with bright red paint.

Photographs posted on Twitter by the cemetery on Saturday showed the marble gravestone daubed with political slogans such as “doctrine of hate” and “architect of genocide.”

The cemetery said the marble tablet was also “smashed up.”

“Senseless. Stupid. Ignorant,” it added of the vandalism. “Whatever you think about Marx’s legacy, this is not the way to make the point.”
