Outside Parliament in London campaigners have been dressing up as George Osborne, Ed Balls and Danny Alexander.
The costumes feature large papier mache heads and brief cases and the stunt was designed to encourage the parties to take the issue of tax dodging more seriously.
Christian Aid has teamed up with other charities including Oxfam and ActionAid to raise awareness about tax avoidance - they say the coalition estimates a tax dodging bill could bring in at least £3.6 billion each year to the UK treasury.
Alasdair Roxburgh from Christian Aid was dressed as Labour leader Ed Balls.
He told Premier: "For Christians we know our teachings are very justice-focussed, around loving our neighbour, making sure we're in a good relationship with the world - and part of that is paying our taxes as citizens.
"We know that when we pay our taxes it goes towards helping the greater good if you like, the whole community, our neighbours - whether they be here in the UK or all around the world."
