On 18th July 2019 the House of Lords debated a motion from Lord Cope of Berkeley (Con) asking Government “what assessment they have made of the government of the United States’ Peace to Prosperity economic plan for Palestine, published on 26 June”. The Bishop of Southwark, Rt Revd Christopher Chessun, spoke:
The Lord Bishop of Southwark: My Lords, I add my congratulations to those already offered to the noble Lord, Lord Cope of Berkeley, on this timely and important debate. As many of your Lordships may know, I generally visit the Holy Land twice a year. Each January, I accompany the Vatican’s Holy Land co-ordination group to the area as the sole Anglican bishop. I have experienced much Israeli and Palestinian hospitality down the years. I am only too well aware of the State of Israel’s just concerns for its security and its safeguarding of the holy places of Jerusalem, but I have witnessed Bethlehem walled in on three sides, Palestinian agricultural land divided and appropriated by military structures, and the acquisition of swathes of the West Bank and east Jerusalem for the settlement of Israel’s citizens and the exclusion of Palestine’s.

The Lord Bishop of Southwark: My Lords, given the recent publication by the Ministry of Justice of figures showing a record level of the incidence of self-harm by prisoners, a record level of prisoner-on-prisoner assaults and a 29% rise in assaults on prison staff, will the Minister acknowledge that we need not only a major reduction in the size of the prison population but increases per capita in resources on a scale not yet contemplated by Her Majesty’s Government? This would give rehabilitation the priority that many now see as an absolute imperative.
