British Prime Minister Theresa May ordered a “full and urgent” probe Saturday into the orgies reportedly staged by senior Oxfam staff working in Haiti after the 2010 earthquake.

The allegations aired in The Times of London are “truly shocking,” May’s spokeswoman said.

“We want to see Oxfam provide all the evidence,” the spokeswoman added.

Britain’s Department for International Development — which gave $43.8 million in taxpayer money to Oxfam in 2017 — also had harsh words for the charity.

“If wrongdoing, abuse, fraud or criminal activity occur, we need to know about it immediately, in full,” the DID said.

Roland van Hauwermeiren, 68, admitted to hiring prostitutes at his Oxfam-provided villa and was granted a month to resign if he cooperated with the investigation, The Times reported.
