10.30am (Rwanda), 9.30am (UK): David Cameron arrives in Rwanda in about half an hour. No floods here, and no need for wellies; the weather is August-in-England perfect. Main task of the day: avoid being photographed looking like you are living it up.

But Mr Cameron is staying in a moderately austere guest house and will be on guard to avoid that photograph with cocktail in hand.
There was a flurry of speculation that he wouldn't be coming at all yesterday. Aides insist they would not have cancelled for political reasons, but they were worried he wouldn't be able to get out of Heathrow because of the weather.
They even had a look at whether they could charter a plane.
Mr Cameron will visit a factory this morning, lay a wreath at a memorial for the 1994 genocide, and hook up with some of the 40-odd Conservative party volunteers who are already out here, working on small-scale aid schemes.
Project Umubano is now about half way through and looking good.
Tobias Ellwood, the party's culture spokesman and carpenter, reckons the refurbishment of Giribuntu school (new classroom toilet and shower block) is on course for completion at the end of the week; there may still be some working through the night to get it completed in time for opening by the minister of finance at the end of the week.
Unusually for a trip of this kind, a handful of Westminster-based correspondents such as me have travelled ahead of Mr Cameron; we've been here since Friday looking at some of the things he will have two days to get a grip on.
Shame he will miss Alistair Burt, the party's local government spokesman and qualified FA coach, who has helped run a series of football projects in Kigali, which came to a glorious climax last night at dusk when he handed over T-shirts and balls to dozens of hyperactive and incredibly promising young players.
Mr Burt makes the telling point that there is no reason why political parties shouldn't act as the brokers for this kind of aid work. There are a lot of people out there who want to get involved in things like this but don't necessarily know how to go about it.
The projects themselves seem to me a bit of a mixed bag. There was a faintly "what I did on my gap year" quality to the sight of Conservative party researcher Corinna Matthews helping build a roof; I know she and her group have done other work as well but that particular exercise seemed to be replacing rather than supporting what the Rwandans could do themselves.
I hope she will excuse my queasiness; the "value added" may well come afterwards, when she and her colleagues proselytise back home.
On the other hand, where there is real expertise, it is being used and appreciated.
On Saturday, we drove into the hills to a medical mission in Kirambe, about an hour's drive from Butare, the country's second city in the south.
There two GPs, Sharon Bennett -- the wife of Andrew Mitchell, the shadow international development secretary -- and David Tibbutt, a retired consultant from Worcester, have been seeing drop-in patients at the rate of about 100 a day.
Some have walked for three hours, been turned away and then come back the next day. The biggest complaints: back pain and muscular trouble, but many have more serious problems.
They are looking to get several women whose pelvic floors have collapsed referred to hospital. They have to walk for hours all the same.
The two GPs are working with nurses and training them as they go; what to spot, what antibiotics to try, and -- sometimes more importantly -- what not to try.
Dr Tibbutt, who has been working in Uganda periodically since 1965, says this has been his most rewarding visit to Africa; the people are so marvellous, he says. A most virtuous circle.
