Nissan leaf has up to 30kWh battery. At 16 p per kWh, it'd cost £4.80 to charge it fully. Can do 107 miles on a charge say Nissan (lets bring it down to 100, because these numbers are never right). That makes it 4.8 p per mile.
Nissan Pulsar is around the same sized car. The most economic version is the 1.5 dCi. Nissan claim 74mpg, but real world reports are coming in at 58 mpg (which is still pretty good). Average price of diesel in the UK is 116.4 p per litre. The same 100 mile journey at 58 mpg, with fuel costing 116.4 p would cost you £9.12. That comes in at 9.1p per mile.
On your electricity cost, that makes the electric car half the price of the diesel for that journey. If you use a petrol Pulsar then the cost per mile rises to 13.2p per mile, and the gap is growing quickly.
It shouldn't be a surprise that it's cheaper to charge an electric car than fill one with petrol. The entire process of refining petrol, shipping it to petrol stations (which takes more petrol/diesel), and then running the petrol stations takes electricity and energy. So the companies providing this need to raise the price of their product to cope with these overheads. With a straight electric charge you cut out the refining, transportation and infrastructure costs which were inflating your petrol price, and get the electricity straight from the grid. You could argue the grid is an infrastructure cost, but you'd be paying that anyway since you live in a building with electricity, and you're still cutting out part of it as you're no longer funding others ability to pay for the grid. When you look at the bigger picture and the system as a whole, it makes sense that it's cheaper to charge an electric car.
