A Catholic peer has called upon the Government to exert greater pressure on Pakistan to stop the persecution of Christians after it admitted that a controversial scheme to “export the dole” involves larger sums of money than previously revealed.

MPs reacted in anger when the press revealed that “up to £300 million” of British taxes was to be given away at Pakistani cashpoints over eight years.

But now Lord Bates, the Minister for International Development, has revealed the figure is in fact far greater.
