this the headlines. prince harry and mcginn‘s have announced they will not continue to do royal duties. they will attempt to repay £21; million on frogmore cottage, which will remain their home. they said they would divide their time between they would divide their time between the uk and north america. today's statement from buckingham palace does not address questions about the couple's attacks in the uk and america and doesn't comment on what

security arrangements would be in place for the royal couple. now it is time for our world. for years, i have been reporting on the uk's voracious appetite for illegal drugs. i have watched the market being flooded by cocaine that's cheaper than ever. so i've come to colombia, where 70% of the world's cocaine is produced, to find out why. i'm getting rare access, a chance to meet the cocaine producers in one of the most dangerous places in south america. in spanish: and to meet the smugglers who are sending the drugs abroad. how many of those shipments would you expect to reach europe? in spanish: criminal gangs are killing anyone who stands in their way. in spanish:

those gangs are never far away. some armed men have been spotted nearby. i want to discover what's happening now in colombia that's making cocaine in the uk more available than it's ever been. for 50 years, colombia was home to the world's longest running civil war, but in 2016, a historic peace deal was signed with the main rebel group, the farc. a new future was the promise — newjobs, new roads — all negating the need for the farc to produce cocaine to finance their political goals. but just a year after signing the deal, cocaine production reached record levels — up nearly a third to around 1.5 million kilograms. i am heading to an area where the cocaine trade begins. this road takes me to one of the main cocaine—producing parts of colombia. what i'm hoping to do here is to meet some of the farmers

who are growing the coca leaves. colombia has spent billions of dollars eradicating coca plantations, so farms are well—hidden. when you come here, you begin to realise how absolutely professional these criminal gangs must be if they can get a tiny amount of cocaine from these remote areas to the bars and clubs of britain. the peace deal weakened the farc, allowing other criminal organisations and dissident farc members to seize control. abandoning political ideology, the groups make cocaine production more efficient. this is a perfect spot to highlight the different gangs that are trying to vie for control of cocaine. from this valley, downwards, is controlled by the clan del golfo. behind me, over there, is the eln.

this side is the eln as well — different branch. the roads at the bottom, they are are controlled by another group called los caparrapos. after hiking for hours, i arrive at the coca field. how old are you? in spanish: shouldn't you be in school — wouldn't you prefer to be in school? in spanish: the peace process promised farmers they'd get help to grow legal crops, roads would be improved so they could access markets, but of the nearly 100,000 farmers who signed up, more than half are still waiting for any help. in spanish:

does it pay well? in spanish: all this effort and you get maybe $150, maybe $220 every two months? these farmers also start the process of turning innocuous leaves into one of the world's most addictive drugs. a shack is well hidden. this is where i'm told the next stage of the cocaine process happens, and i'm told it's disgusting. i can assure you, it certainly smells awful. in spanish:

first, they add limestone, then ammonia. in spanish: it's hard to believe that people will snort all these poisons — not to mention the environmental destruction they cause. the chemicals that they are adding will run off down the hill, into the rivers that we have been walking through today. guys, we have to leave. 0k. there are people coming, there are people coming. some armed men have been spotted nearby. this emphasises how dangerous this entire region actually is. in the dead of night,

the young men return and continue the production process. the incident that made us run turned out to be four members of the clan del golfo being arrested by the army. when we left last night, this was covered in leaves, so all those leaves become this? in spanish: can i smell it? it stinks. the next stage is add heat to remove the water and turn it into pure cocaine paste. then it's sold to the criminal gangs. they run crystallising labs, where they will add more strong chemicals, such as sulphuric acid, and turn this paste into white cocaine powder.

in spanish: so if you could produce more, you would produce more? in spanish: there's lots of people have been killed in colombia because of cocaine. in spanish: violence is spreading across colombia. a coca valley in south—west colombia has turned into one of the most dangerous regions of the country since the peace deal was signed. this is home to the indigenous nasa people. there are nearly 200,000 of them and colombian law grants them

the right to rule their ancestral land. they live out here, in these rural areas, in the hills and mountainsides — and this area used to be controlled by the farc. exercising their rights meant that, for decades, the nasa suffered under the farc. but since the peace deal, things have got even worse. as different gangs now compete for territory, the nasa are being attacked from all sides. more than 50 of them were killed last year. the un has described their situation as dire. in spanish:

wilmer invites me to attend a meeting of some of the victims of the violence but, before we set off, he insists we perform an ancient custom. this is a spiritual ritual that the indigenous tribe perform before they go to anywhere dangerous and, essentially, you have to walk in a certain way towards this circle. under this rock? in spanish: record levels of cocaine production are only worthwhile when the drug can reach its foreign market.

these roads are of strategic importance. so the reason this area matters to the gangs, the criminal gangs, is not because of what's grown here? in spanish: throughout the journey, wilmer is nervous, intensely focusing on each vehicle we pass. in spanish: it is an uneven fight and ijust wonder why you don't let them use the routes. in spanish:

the consequences of opposing the gangs soon become very obvious. so what happened here then? in spanish: cristina bautista was a 30—year—old indigenous leader. in spanish: but her bravery made her a target. just ten days before my arrival, she was killed alongside her four indigenous guards. we finally arrive at

the village of tacueyo. this meeting has been organised by the peace commissioner, forced by a spate of killings to confront a community that feels abandoned by the government. in spanish: applause. just tell me about cristina. what sort of person was she? in spanish:

the peace deal was negotiated by the previous president amid opposition from many members of the current government. they have been in powerfor almost 18 months under the leadership of president ivan duque, who has been accused of failing to support the agreement. i grabbed the chance to put the concerns of the nasa people to the peace commissioner. so a lot of people in this area believe the recent violence is a direct consequence of this government failing to stand up for the peace deal. that is — they never said that. they tell that to me. the peace agreement was designed to be implemented in 12 years. we are beginning. we are in the transitional process. so this is not the reason, the reason is not the trafficking. i don't know if they told you... but... no, absolutely. is this an interview? this is being filmed. is that — are you ok with that?

yeah, but i need to be prepared for that because you are asking me questions... 0k. um, right. because we were trying to get an interview with you in bogota next week. yeah. we will do that. but the interview never happened. and with that, off went the government officials by military helicopter, rather than riding risky, rutted mountain road. the nasa people have their own blue uniformed security guards, of whom canas verdasco was one. in spanish: last february, he was part of an unarmed team that recovered these weapons and arrested eight farc dissidents. the incident made him a target and in october, the father of six was assassinated in front of his wife. in spanish:

wearing this uniform increasingly requires courage. this man survived the ambush that killed cristina bautista. given what you have seen, and the dangers involved, why do you continue to do this? in spanish: the violence is driven by the vast fortunes to be made getting cocaine from the mountains to the markets.

this northern part of colombia, by the caribbean coast, is hugely significant for growing bananas. but the huge number of containers needed to send the bananas overseas provides a perfect opportunity for the drug smugglers to send cocaine abroad as well. this is the port of zungo embarcadero, a key smuggling spot. the shallow waters mean containers are carried by tugs to a floating port three hours away, where large ships will take them on to europe. i'm off to meet a man who sends up to a ton of cocaine to europe each month. and he's not the only one. dozens of smugglers use the port, working for different groups, but all paying taxes, access charges, to the clan del golfo — currently the biggest organised crime group in colombia. how easy is it to transport cocaine out of colombia? in spanish:

for real?! in spanish: in any one year, you will try to get

12 shipments to europe. how many of those shipments would you expect to reach europe? in spanish: how much do you get paid for sending this through? in spanish: so you make about $150,000 per shipment? and you've been doing this for six or seven years, so you have earned millions doing this. in spanish: do you take cocaine? no. why? in spanish:

but others are not so squeamish. colombia's most famous export has never been in greater demand in the uk. before heading to columbia, i met someone who was interested in talking to the farmers. so earlier, i asked you did you know what happened to the coca plant and you said no, so i want you to have a look at this video. in nottingham, meet 25—year—old lewis bradwell. he started taking cocaine as a teenager. what was a regular habit is now an occasional hit if friends are doing it. he's keen to know about the origins of the drug and readily agrees to chat to the farmers, so we arrange a 6,000—mile conversation about cocaine. so you never take cocaine yourselves? in spanish:

smart lads. in spanish: you feel a buzz, a rush, uplifted. you have plenty of energy. you could stay awake for two or three days on end. yeah, afterwards, you feel terrible. you feel crap the next day. in spanish: i started when i was probably about 19. it's put in front of us everywhere. i've seen it from a young age. you can't really get away from it. in spanish: that was the main reason i wanted

to stop doing it in the first place, because the cost was through the roof. i would be spending £200 easily — £200, £300 a week — which is your two—month wage easily, every week, just on cocaine. it's been an eye—opener talking to you both. i am shocked how young you both are. and no—one, at 16 years old, should be dealing with such stresses of getting you 12 years in prison or getting killed by another rival gang. in spanish: thanks, guys. some areas of colombia are facing a perfect storm.

they feel the government has failed the peace process, allowing new murderous gangs to exploit the vacuum. they, in turn, are eyeing the vast fortunes to be made supplying increasing demand from wealthy foreigners for cocaine. both production and consumption of the drug are at record levels, leaving these communities feeling ignored and helpless.

hello there. for the past few weeks, it has been pretty wet, windy and very mild, with temperatures well above the seasonal average, but this weekend will be a welcome change for many others to see more in the way of sunshine, thanks to sunshine and high pressure that is built—in. they weather the blustery showers across northern as a pressure continue to retreat away from the uk. for this working week, it looks like it will stay mainly dry, thanks to high pressure and plenty of sunshine around, but it will stay cold with frost and overnight fog patches. not just for the weekend, this high pressure will stay with us into next week, could see some weak weather fronts toppling in an bringing figure cloud at times, but for much of monday into friday, it is high pressure, but then it could retreat off into the continent and allow for weather systems to me then. part two at this weekend the lots of very cold and frosty, quite a hard frost

out of town and is a mist and fog to that could be slow to play in places. a bit of a change taking places. a bit of a change taking place across the north west of scotland, more breeze and cloud here and possibly some rain for the northern ireland, but less cold here with 10 degrees. in a way, whilst elsewhere it will be sunny and chilly. through sunday night, with more cloud in the north, it will be further south colder, high pressure dominating as well. hi frost is likely to greet monday morning with some mist and fog patches too. 0nce again, some sunshine across this country and even further north, parts of northern ireland and scotla nd parts of northern ireland and scotland should see some sunshine, but more cloud and ways across the north—west, so less cold further south. 0n north—west, so less cold further south. on tuesday morning, we do it all again with a bit more cloud across the north, so less cold start here and frost frosty and foggy further south. this week weather front on tuesday will go south,

introducing a band of thick cloud that could produce a bit of gentle at times. initially in scotland and northern ireland, then into northern england and perhaps into wales. a bit of cloud into northern england and wales perhaps on tuesday, with some sunshine coming across scotland for a time. a cooler day in scotland though, temperatures in single figures here. even further south, a chilly day to come. for wednesday, a messy picture with variable cloud. quite a bit of cloud around, but some sunshine in between. another cool day, temperatures ranging from around seven to 10 degrees. for the rest of the week, largely dry thanks to that area of high pressure. variable amounts of cloud with a bit of sunshine around as well, and temperatures rising for the weekend. back you our pressure chart. 0ur area of high pressure will retreat into the near continent to the end of the week and we will see some weather systems ganging up on us because of the jet stream, which

will start to invigorate and take aim across the uk. when that happens, it would be steering low pressure systems to our shores. that will be for the following weekend and beyond, where it looks like it will turn more unsettled. for the upcoming week, it starts fine, pretty cold with some sunshine and variable cloud, and then decides that as a head into the following weekend is the low pressure is starting to bring rain and went back to our shores.
