For weeks, celebrities have been embracing the charity ice bucket challenge – and now the stunt has arrived at the Bank of England (BoE).
Former BoE Monetary Policy Committee (MPC) member Andrew Sentence told CNBC on Thursday that he had taken up the challenge himself, and nominated the entire rate-setting committee to do the same.
In response, Sentence said just one member of the MPC had agreed to do the charity dare.

"I can't say who has agreed, but I nominated the whole committee," said Sentence, refusing to name the mystery volunteer.
Sentence was nominated by HSBC's Chief Economist at HSBC Stephen King.
Sentence's calls for interest rate rises have also been ignored by the MPC. The BoE left rates at historically low levels on Thursday, keeping rates at 0.5 percent, despite improving economic data.

Thousands of people worldwide have braved the freezing water challenge to raise awareness of neurodegenerative disease ALS. The stunt, which went viral last month, has been accepted by pop stars like Justin Biber, former U.S. president George Bush and even Prince Albert of Monaco.
