I'm not very familiar with Venezuela. I tend to glance at the odd few reports on how despite the promising first years of Chavez and the using of the oil boom to greatly reduce poverty, the PSUV had long flown off the rails in the country, and things have been descending into crime and economic hardship with stall in oil prices, and opposition protests supposedly banned and repressed. I feel for you guys truly, but I don't generally tend to celebrate the idea of a right-wing party taking over, and nor am I very optimistic that even in such an event of an electoral victory and a change in administration, that change will be greatly tangible or beneficial for the right people. I dunno.
As for the UK, I'd like to see a form of federal system, just to help blow away some of the stink of a centralised Westminster pampering only monied Londoners and the Home Counties, while having little interest in the North and in Wales. It's not going to happen though. The main parties are likely going to go to war over piecemeal post-referendum questions like West Lothian, let alone practically come up with ways to implement such a system when England is so disproportionally larger in geography, population and in economic terms. Divide England into regions, like super-counties? That'd mean artificial boundary lines and demarcations would have to be drawn. Places like Lancashire (with Greater Manchester?) and Yorkshire might work, but where does one stick Cambridge with? East Anglia?
Do away with the antiquated House of Lords. Have an elected second chamber. It works for Germany, Canada and Australia.
