intu derby is the city's main indoor shopping centre. it opened in 2007 as westfield derby after extension work costing £340 million, subsequently being sold to intu in march 2014. it contains a food court and a 12-screen cinema (showcase – cinema de lux) which was opened in may 2008. the development was controversial and local opponents accuse it of drawing trade away from the older parts of the city centre where independent shops are located. some of these experienced a downturn in trade and some have ceased trading since the development opened leading to the "lanes" project which eventually became the second bid and the formation of st peters quarter. in the centre itself, a combination of high rents and rising rates have made things difficult for smaller traders.
