A woman who spends her day in prayer and looking after vulnerable people is leading 1,500 nuns, monks and friars in a protest launched by rock star Bono. Members of religious orders are calling on MPs to Make Poverty History.
Sister Pat Robb, a nun in Cambridge, said: "We are speaking out on behalf of the 1.3bn people worldwide living on less than a dollar a day."
It is one of the biggest protests by religious people at Parliament since the 16th century Reformation.
End needless poverty
The event, part organised by CAFOD, is the first time religious orders have come together for a mass lobby of Parliament.
Sister Robb from the Congregation of Jesus said: "We will not stand by and let our politicians get away with this any longer.
"This year is an unprecedented opportunity to end the needless poverty and hunger, and the human despair this brings.
"Many of us have worked in developing countries and seen the suffering of our brothers and sisters.
"The Gospels demand we take action against poverty."
Pop stars, actors, politicians and ordinary people are campaigning for an end to Third World debt.
