Keir Starmer, the leader of the UK Labour party, has not endorsed Justin Welby, the Archbishop of Canterbury, who is under increasing pressure to resign following a report on the church's handling of abuse by John Smyth.

Smyth's abuse occurred in the UK during the late 1970s and early 1980s and later in Zimbabwe and South Africa, affecting approximately 130 boys.

An independent review suggested the abuse might have been addressed legally if reported earlier to the police by the church.

Prime Minister also expressed that the victims were 'failed very, very badly,' but refrained from suggesting Welby's resignation.

Speaking from the Cop29 summit in Baku, Azerbaijan, Starmer labeled the allegations as 'horrific' and emphasized his sympathy for the victims, urging the church to resolve the matter.

Several victims and clergy, including Bishop Helen-Ann Hartley of Newcastle, have demanded Welby's resignation.

Andrew Morse, a victim who attended Winchester College, argued for Welby's resignation as a gesture of solidarity with victims.

Stephen Cherry, a former canon of Durham Cathedral, also supported Welby stepping down for enabling significant change.

Despite considering resignation due to his 'shameful' inaction reported in 2013, Welby apologized but decided not to resign, according to Lambeth Palace.

Smyth, a barrister who abused boys at evangelical camps, passed away in 2018.
