found guilty of gross misconduct will be sacked — under new powers being given to police chiefs. the move has been prompted by the convictions of former metropolitan police officers wayne couzens, who murdered sarah everard, and the serial rapist david carrick. our home editor, mark easton explained how the changes will look in practice. instead of having three lawyers, you will have on the chair a senior police officer, chief constable or one of his or her deputies, then you will still have two independent people, a legal professional and a lay person. so it sort of gets us a little bit further down the road. don't think in a way this is going to please anybody because i've already heard chief constables say it's not enough, we need to have real control of this, they can be outvoted by these independent voices and there is some frustration about that. then on the other side of the argument, people like the police federation, which represents rank—and—file officers, say these will become a kangaroo court, that basically this is as they say a retrograde step that takes us back to the days when senior police officers were acting essentially as judge and jury in these disciplinary cases, there were marking their own homework and came to these hearings having already decided that these were officers they wanted rid of. let's hear now from the police federation — that's the staff association for police officers — and their national chair, steve hartshorn. good to speak to you, steve. the government is saying that these changes will make sure that there is no place to hyper officers who do not deserve to wear the uniform. do you agree?— you agree? good afternoon. i don't, to be honest. _ you agree? good afternoon. i don't, to be honest. i _ you agree? good afternoon. i don't, to be honest, i think— you agree? good afternoon. i don't, to be honest, i think the _ you agree? good afternoon. i don't, to be honest, i think the current - to be honest, i think the current police regulations are fit for purpose, i think this is simply a move to cover up for the inadequacies and poor performance of previous chief constables, commissioners, senior leaders who have failed to get to grips with the very basics of leadership, culture and dealing with vetting at a high level. this is theirfault, they have messed this up over the past ten to 15 years and now they want to change the law to suit themselves, that's not fair on police officers. none of the changes they are seeking for today were had prevented anything to do with wayne couzens, thatis anything to do with wayne couzens, that is down to poor investigation. what you make of the idea that chief constables will present of a misconduct hearing is? i constables will present of a misconduct hearing is? i think it will be returned _ misconduct hearing is? i think it will be returned to _ misconduct hearing is? i think it will be returned to the - misconduct hearing is? i think it will be returned to the bad - misconduct hearing is? i think it will be returned to the bad old | misconduct hearing is? i think it. will be returned to the bad old days and as your previous commentators had we believe it will return to a kangaroo court where people, such as the chief constables with a ride with a preconceived set of ideas and will have already found colleagues guilty irrespective of evidence to stop it is simply wrong, it is biased, not independent, these are comments that came to the government when we had changes to the current 2020 regulations about the old regulations so we are taking a retrograde step, to some extent. but ou have retrograde step, to some extent. but you have people who brought these changes in including the met commissioner sir mark rowley who publicly campaigned for these changes, so he wanted independent lawyers to be replaced by chief constables overseeing these processes because he believed that lawyers, and quote, are more forgiving of bad behaviour. so surely that's a good thing if you have people who are more critical understanding of the processes and therefore are going to make sure that bad behaviour is rooted out? if you look at the data, it's fairly conclusive as to what standards mean in terms of legally qualified independent panels now, i would say they are about the same but of course things need to have all, some of the new regulations have only been updated as late as august 2022 so haven't had a lot of time to bed the new legislation before chief constables and commissioners are asking for the law to be changed so i think there's more to be done. we do not think that putting chief officers back in charge will be anything to restore public confidence or even offers a confidence or even offers a confidence and how they will be

have a bit of a split in the weather today. we've been watching rain coming in from the southwest, pushing northeastward courtesy of this clutch of weather fronts. a ridge of high pressurejust keeping things more settled across the north and the east and this is where we'll have the driest weather through the rest of the day and also some sunshine. but the rain's continuing to advance slowly, northwards and eastwards. it is weakening as it does so, there'll be a bit of a gap behind it across south wales and south west england. but by the end of the afternoon, we'll be seeing some heavy thundery downpours coming in across the south west, with top temperatures in plymouth, 20 degrees. 15 in birmingham, and then we go into the sunshine on the other side of the weather front in newcastle, with 18 degrees. patchy rain continuing across northern ireland, getting into south west scotland, but a lot of sunshine in scotland. here's where we'll have some clear skies overnight, as we will across some southern areas. our frontal system continuing to move northwards. it's going to be a mild night for most of us, but a chilly one in sheltered glens, with temperatures slipping down to about 3 or 4. so potentially a touch of frost tomorrow morning. so here's our weather front tomorrow across northern england, southern scotland and northern ireland. ahead of it, we hang onto the sunshine. behind it, there'll be some sunshine with the early morning heavy thundery downpours clearing away. temperatures, 1a to 22 degrees north to south. then as we head into the weekend, high pressure really does establish itself across the uk. but we are watching the progress of this weather front. it's going to bring in a bit more cloud on saturday into the far north of scotland through the day. here, too, it's going to be pretty windy. we'll have low cloud, mist and fog in southern england and northern ireland to slowly lift. but in between, a lot of dry weather and also a fair bit of sunshine, with temperatures 15 in lerwick to 23 in london. then as we push on into sunday, high pressure still very much with us, but that weather front encroaching a bit closer, bringing in some rain. and again, gusty winds out towards the north and the west. any early morning mist and fog lifting to leave most of us with a dry day, again with a fair bit of sunshine and highs, 16 to about 23 celsius north to south. then as we move on into next week, well, that high pressure is still very much with us now. we could see one or two showers getting into the south of england on tuesday, still open to question, but it's going to be pleasantly warm for the first half of the week. live from london. this is bbc news more than 70 people including several children are killed in a fire at a block
