David Hillman, spokesperson for the Robin Hood Tax campaign, said:
"Bob Diamond can only be hiding his bonus because he fears it will look unreasonable to most ordinary people. His potential pay package alone would keep hundreds of nurses and teachers in jobs.
"When even in a bad year Barclays reports nearly £6 billion in profit, it's clear the banking sector is protected from the long-term consequences of their risky behaviour, whilst ordinary businesses and families are left to pick up the pieces.
"Like all our big banks Barclays enjoys a multi-billion pound implicit subsidy courtesy of the UK taxpayer. It is high time they balanced the books by making a multi-billion pound contribution back to us."
