London's electric car company NICE (No Internal Combustion Engine) says it expects to build sales under new mayor Boris Johnson.

That's thanks to a combination of exemption from the capital's congestion charge, free parking and growing concern among Londoners over the spiralling cost of petrol and diesel.

"We know that Boris recognises the many benefits of owning an electric car," said Julian Wilford, co-founder of NICE cars.

"But we also understand the importance of choice to the mayor - and to our customers. At the NICE Car Company we have the widest range of zero-emissions vehicles on the market and hope the new mayor will find time to visit our West London base to learn more."
