Prime Minister David Cameron sent his best wishes to Christians celebrating Easter, saying it was an "exciting time for the faith" and paying tribute to the Christian principle of charity, as shown in the government's spending in overseas aid. He said:
"This year’s Holy Week and Easter celebrations follow an extraordinary few days for Christians.
“In the Bible, Saint Peter reminds us of the hope that comes from new birth through the resurrection of Jesus Christ. As Christians, it also reminds us of Jesus’s legacy of generosity, tolerance, mercy, and forgiveness.
“That legacy lives on in so many Christian charities and churches both at home and abroad... As long as I am Prime Minister, they will have the support of this Government.
“With that in mind, I am particularly proud to lead a Government that has kept its promise to invest 0.7 per cent of our gross national income on helping the world’s poorest...I hope you have a very happy Easter.”
