rachel mwikali is a feminist and an activist in mathare, one of the biggest slums in the capital. the march is straddling two wards with different politics. if kenyans are told the election was free and fair, they won't go to violence. of that, i'm sure. even in the slums, as much as they are using words to criminalise us, telling us it's a hotspot, if they know the election is free and fair, they cannot disturb. rallies have been romping across the country for weeks. this is opposition orange, and green, and blue and white. the national super alliance, they're called, nasa, five opposition parties on one ticket. raila odinga is their presidential candidate, son of the country's first vice president. since then, the odingas have always been in opposition. it's his fourth attempt to get the top job, and at 72, probably his last, and that makes the stakes even higher. "the car is red", the sign reads, "the driver is drunk

and the conductor is a thief". yes, red is the colour ofjubilee. drivers and conductors aside, their alliance won the last election. their candidate is the incumbent. uhuru kenyatta, son of kenya's first president. the big political dynasties live on more than 50 years after independence. the success of this whole ballot depends on what happens in this building. the independent electoral and boundaries commission, or iebc, is the arbiter of the whole process. in a country where vote—rigging has been suspected in the past and is expected in the future, their computerised voting system is the key to free and fair elections. if it works, fixing the result will be an awful lot harder to get away with. the public demonstration went well, but if the computer system fails, kenya has a big problem.

and given what has happened in the past week, people need reassuring. chris msando was the acting head of it at the electoral commission, responsible for the computer. "the system's safe with me", he said, but then he disappeared. this time last week, he left the iebc building and went just around the corner to club 7. he was a local. he was meeting a 21—year—old graduate student known as carol. what happened over the next few hours is a lot less certain. his land rover was seen driving across nairobi. cameras picked up images of the car. at one point, four people may have been inside, a large woman in the front seat. elsewhere, he was on the phone looking agitated. then the trail went cold. first, his car was recovered on one side of town. then on the other side of the city, two bodies were discovered. chris msando had been tortured. both he and the young graduate, carol ngumbu, had been strangled to death.

people jumped to their own conclusions, and it's put the country on edge. a senior kenyan lawyer wants a commission of inquiry for this and other cases of what he calls forced disappearances. apart from being a chilling effect on the general populace and even other employees of the electoral body, it againjust highlights how we have, for too long, left extrajudicial killings to go on unaddressed. corruption is a huge part of the problem. this footage was filmed by citizen journalists. it shows police accepting bribes. it's common, and just the tip of the iceberg. the police officer stops, opens the door and grabs something. john—allan namu is an investigative journalist for africa uncensored in kenya.

corruption is endemic in this country. it's taken over very many parts of government operations. a third of our resources are believed to be lost or misappropriated every year. it's driven by a lot of private—sector impunity, and impunity is the word. nothing ever gets resolved. no one ever goes to jail. that's the bigger issue in kenya. ten years ago, terrible post—election ethnic violence killed more than 1,200 people amid claims that it was rigged, but nobody has faced justice. that's why people are so afraid now. international criminal court charges against the deputy president and president kenyatta collapsed when witnesses died mysteriously. at the last election, the computer system failed. rachel's friends in mathare are worried it will happen again. we are a bit scared, especially as women. the way things are going, we are all scared. he's saying the main issue we have is now about the rigging of elections. she's saying it will be peaceful as long as it is a free,

fair and credible election. but if it isn't free, fairand credible... and what happens? this is obviously a group of opposition supporters. what if raila odinga doesn't win? we want to live in a peaceful community, but if it happens by mistake, the jubilee government rigs elections, we, he's saying we as nasa supporters will have to fight with the government. if he loses, but it's a fair election, what happens then? if raila loses, people will be ok. nothing will happen. but if it is 50-50, we will not agree on that. so if it's really close, there's more chance of being violence? yeah.

this is one of the most important elections in africa, in one of its more hopeful democracies. what's significant now is not who wins, but how the loser takes defeat. in the three years since the birth of the so—called islamic state it is believed up to 850 men, women, boys and girls have left britain to make what for most of us would be the unimaginable journey tojoin the caliphate. many are since believed to have been killed or now find themselves trapped in raqqa as coalition troops close in to liberate it. remarkably, some of those confronting isis across the syrian battlefields are themselves from britain. over the years, dozens have left these shores as civilians to fight the jihadists. mostjoin regiments from the kurdish ypg army. 0ne young man, ryan lock,

was praised this week as a hero by a coroner who heard details of his death. he shot himself to avoid capture after being injured in a gunfight last december — the third briton to die fighting isis. others who have fought have been arrested on their return to britain. i'm joined now by vasilika scurfield, the mother of eric scurfield, who was killed in 2015 as he fought with the ypg. i am so sorry for your loss. why did eric, or costa, as the family knew him, why was he so keen to get involved in a war that in many ways have nothing to do with him? he felt that since most of the people fighting in syria for isis, many of them were british soldiers or most were from other countries, he felt that it was his duty to redress that balance. and he felt that isis was a threat that if not

stopped, would spread. what if isis had not been stopped by the kurds? they might have gone on tojordan, the greek islands, albania. they were unstoppable at the time and he felt he had to step up. and i think he was doing his national service in the greek army at the time he formed this ambition. actually, he was in the royal marines here in the uk. part of the reason why he went was disappointment when he was told by his ceos that there was no chance of him going in to rescue the 10,000 yazidi people in the mountains. he was disgusted. and of course, the government at the time was keen to offer support to precisely the sort of militias that he ended up fighting with. they lost a parliamentary vote, which makes it all the more remarkable that the status

of fighters like your son is, well, how would you describe it? it is a sort of legal limbo. it is worse than that. they are often criminalised when they come back. so these are guys fighting with coalition forces. they are getting our support from coalition forces. they are getting treated, if they are lucky enough, in special forces field hospitals, for example. so they are working closely with coalition forces and they are being treated as terrorists when they come back. i understand that we have to question them to check which side they are fighting for and make sure they have not committed a crime. but after that, you find some of them are let go and some of them are criminalised and put on bail, where they have to present themselves three times a week for six months at a time. theirfamilies are treated disrespectfully. i know there is a sort of covert network of families, but you have to be careful city reasons. the first is the islamic state's vigilance on computer networks being unknowable.

secondly, you have to shield your family members‘ activities from the british government? it is more about privacy. for a lot of parents, it is a shock, but it is those things as well. they are soft targets for any maniac who might want to go after them. and they are at risk from being treated disrespectfully by the british government. i have no complaints about the way i was treated, and i don't see why other parents should not benefit from the same treatment. what would you like the government to do formally? i think they should be stopped at the airport when they come in. when they establish from their phones and the evidence that they were fighting from the ypg, they should as a minimum just be let go. they don't have a policy across the uk to say everybody will be treated the same way. half of them coming and are not bothered,

and half of them are criminalised. it seems to be a lucky dip. how many british people do you think are out there? it would be a complete guess. we are told there are up to 200 foreign volunteers from all countries, 12 greeks, some chinese, people from all over europe, the usa, canada, maybe up to 50 brits? and at least one of them is a woman. did you try to stop him going? of course i did. the whole of the might of the british military tried to stop him going, but there was no way we could. he was determined to go. it may be that every answer is different to this question, but what do they have in common, do you think, the men and woman that have gone out there? courage. and the strength of their convictions. many thanks. i should say that we asked

the home office whether all britons who go to fight against isis were at risk of prosecution. in a statement they said anyone who returns from the conflict in syria or iraq should expect to be reviewed by the police and that charges would be considered on a case by case basis. before we go, if you're about to head off abroad and fancy some inspiration for your holiday snaps, why not head to the university of greenwich for an exhibition of some of the best ever entrants to the travel photographer of the year awards? the show opens today. if you can't make it, here's a taste. good night. hello once again. if your holidays are taking you to southern europe be mindful there suffering a heat wave at the moment and if you're closer to home, no dangers of that but sharp thunderstorms to be had initially in wells on saturday and then moving to the midlands before they get to east anglia and the south—east. charmed life in the south—west of england, fewer showers
