aleem maqbool, reports. five turbulent days after a damning report, justin welby has contacted the king and resigned. that report criticised the church of england and the archbishop of canterbury for their handling of the case of one of the most prolific abusers associated with the church. justin welby initially apologised, but said he would not step down. today, he changed his mind. in a statement, the archbishop says...

the archbishop of york, with whom he has worked closely for many years, said it was the right thing to do, but it had been a difficult time. today is a day of sadness. i am sad for him, i am sad for ourchurch. i'm desperately sad for the people who have been hurt and abused because of the church's failings and by people who were acting in the name of christ. it is a shameful thing. but i believe his exercise of responsibility in this is a sign for all of us to accept our own responsibilities. in this case, it was accepting responsibility for failings in dealing with this man, who abused at least 120 boys. the first cases of abuse by john smyth at christian summer camps were in the mid—19705. by the early 1980s, church officials were informed, but there was what the report calls an active cover—up. in 1984, john smyth carried on his abuse in zimbabwe

and later south africa. we know the archbishop of canterbury was definitely told by 2013, but the abuse continued and was exposed by channel 4 in 2017. smyth died in 2018 without ever facing justice. in azerbaijan, sir keir starmer was asked about the case. what i know of the allegations, they are clearly horrific in relation to this particular case — and both in their scale and in the content. and my thoughts, as they are with all of these issues, with the victims here, who have obviously been failed very, very badly. hours later when the archbishop resigned the prime minister said he respected the decision. there is no timeline yet as to when the archbishop will vacate lambeth palace or how long it will take to replace him.

for now, the church is dealing with the news that the man who led it for nearly 12 years is on the way out. aleem maqbool, bbc news. joining me is francis martin — reporter at the church times. thank you for being with us. did he have to go, do you think? ., , did he have to go, do you think? . , , think? there have been calls for him to — think? there have been calls for him to go _ think? there have been calls for him to go since _ think? there have been calls for him to go since the - think? there have been calls| for him to go since the report was published. there've been calls for the archbishop of canterbury to resign previously on this issue. he said on thursday that he would not resign. and today he did resign. and today he did resign. the question really is what happened in the interim for that we can only assume that as per his statement today where he said he didn't believe it was in the best interest of the church for him to continue, within that period of time he changed his mind. about whether it really wasn't hit best

interest of him to continue as the archbishop of canterbury. how devastating do you think this is for the church of england?— this is for the church of encland? �*, . , . england? it's an unprecedented situation and _ england? it's an unprecedented situation and that _ england? it's an unprecedented situation and that this - england? it's an unprecedented situation and that this hasn't i situation and that this hasn't happened before in the long history of the church of england. what will be in some ways the bigger challenge is the challenge of systemic safeguarding failings in the church. this is what the report highlights. the focus on the archbishop of course is natural. he is the leader of the organization. and obviously the organization. and obviously the calls for him to resign and this decision today have captured the headlines. but beneath that there are bigger, broader, deeper questions about safeguarding in the church of england that have been asked for a good many years and will perhaps continue to be asked until more progress is made. with those questions do you think there could be more

resignations? it think there could be more resignations?— think there could be more resignations? it is possible. man of resignations? it is possible. many of those _ resignations? it is possible. many of those who - resignations? it is possible. many of those who called i resignations? it is possible. | many of those who called for justin welby�*s resignation has said it shouldn't stop here, there should be further resignations. they have been questions about other figures outside of the church of england who are mentioned in the report. the police for example and questions about their investigations from 2013 when they were informed by the church. and yet no investigation really got off the ground fully until 2017. yes, there are many more questions and we will be hearing those i'm sure over the coming days and weeks. what hearing those i'm sure over the coming days and weeks. what do ou think coming days and weeks. what do you thinkjustin _ coming days and weeks. what do you thinkjustin welby's - coming days and weeks. what do you thinkjustin welby's real- you thinkjustin welby's real crime was? in the end was it negligence, he should have done more, hejust didn't negligence, he should have done more, he just didn't do enough? in terms of what the review says, yes, it highlights the

fact that more could have been done byjustin welby, by lamberth palace, the church of england when they became aware of the abuse ofjohn smyth, horrific abuse over a0 years. in terms of his resignation, again, that issue of not having done enough. yes but there also theissue done enough. yes but there also the issue of safeguarding in the issue of safeguarding in the church of england, not having progressed to the point that people expect. and that is something that will continue to be debated. something that will continue to be debated-— be debated. good to talk to ou. be debated. good to talk to you. francis _ be debated. good to talk to you. francis martin - be debated. good to talk to | you. francis martin reporter be debated. good to talk to i you. francis martin reporter at the church at times on the resignation of the archbishop of canterbury. around the world and across

the us state department now says ten thousand north korean troops have sent to russia and that they've begun engaging in combat operations. there are already questions about what donald trump's return to the white house injanuary will mean for the war with ukraine. this week the kremlin denied press reports that mr trump had a call with the russian leader vladimir putin. joining me now is patrick bury, defence expert at the university of bath and former nato analyst. thank you very much for being with us. what do you think the role of these north korean troops is going to be? good evening. — troops is going to be? good evening, ben. _ troops is going to be? good evening, ben. it's— troops is going to be? good evening, ben. it's most- troops is going to be? good i evening, ben. it's most likely to be used in the kursk first because it's expedient for north korea or more politically

expedient to them to be used on russian territory rather than attacking ukrainian forces inside ukraine proper. i think the numbers were not 100, maybe up the numbers were not 100, maybe up to 10,000, which is a division, not all of those would be combat troops. essentially what they will do is allow that extra mass. we know it's an attritional kind of warfare that the russians are using. they have diverted a good amount of their replacement troops, they are regenerated troops towards kursk. i think they have a sense of urgency given the change of administration in the us of trying to take that crowd back or at least getting as much of its own russian territory back from ukraine before there is any real negotiation.— before there is any real neuotiation. , , ., negotiation. just to remind eo - le, negotiation. just to remind pebble. kursk— negotiation. just to remind people, kursk is _ negotiation. just to remind people, kursk is the - negotiation. just to remind people, kursk is the area l negotiation. just to remind - people, kursk is the area where ukrainian troops mounted in incursion into russian territory president zelensky says actually, that incursion is tying down 50,000 russian

troops at the moment. but the new york times has been saying that actually, the russians it may be preparing a counter offensive and that they've got about 50,000 troops, including the north koreans who are ready to launch a counter offensive. what is your reading of that, what do you think would happen next? , , r' next? this is it, the kursk operation. _ next? this is it, the kursk operation, the _ next? this is it, the kursk operation, the incursion i next? this is it, the kursk. operation, the incursion will bejudged on its ultimate outcome and wejust bejudged on its ultimate outcome and we just don't know yet. 0ne outcome and we just don't know yet. one of its stated goals is to try to draw it russian forces in the front line and other parts of ukraine to make them go round towards kursk. it didn't really do that. there was no major change for that what it is doing is sucking in the regenerative forces, the newly trained or not even well—trained but newly formed forces that are being sent along with more elite units who are actually in the heavy fighting there. it's a double—edged sword for ukraine.

yes, it is 50,000 troops and may be 10,000 ukrainians they are at a stretch. they are already, the russians are starting to attack ukrainians have done counter offensives, smaller ones. generally it looks like the russians are building up with probing attacks. i would expect to see some large, given the way the politics is going some sort of large attempt to take back mainly the central town. also while all this _ mainly the central town. also while all this is _ mainly the central town. also while all this is going - mainly the central town. also while all this is going on - while all this is going on in kursk, the russians seem to be making slow but steady incremental advances along the front in the east of ukraine. they are. it's at a more moderate pace than it was for them it's a quicker pace that was previously, sorry very slow, very costly and now they are starting to speed up. it's are starting to speed up. it's a very huge cost. as the chief

defense staff said on sunday russia are taking 1500 killed and wounded a month, which is the highest sense the start of the highest sense the start of the war in 2022. that's a huge amount of casualties i think it does indicate this recognition in russia that now is the time to really try to push through its advantage for that we know the ukrainians are under pressure morale is not great with this big question about continuing us support and also potentially these negotiations coming down the line. on the russian side this idea that actually they are economy is starting to heat up and potentially this is their window of opportunity now that they could actually go on to be in a weaker position if the work continues with them attic is a mixture of those things, you're going to see them try to really continue the events they have both in donbas and expecting something in kursk two. ., ., expecting something in kursk two. . ., two. patrick, thank you as ever. defense _
