I would have thought London would have plenty of potential polling stations, such as schools, churches and lighthouses, before resorting to temporary options. However, my second closest station was a Portakabin, only slightly larger than the pictured shipping container. I suppose the mysterious tradition of holding the election on a Thursday meant potential schools would still be full of noisome nippers.
Another quaint custom is the use of the first-past-the-post system, which has resulted in the UK being governed by a party which only a quarter of people desired. I am more familiar with the Australian combination of preferential and proportional representation, which leads to grumbling by only half of the voters.
