Lamp - needs electrical fix (EH5, Granton, Edinburgh)

Giving away this brand new lamp, complete with light shade and bulb. I've realised it has an electrical fault and too late to take back to the shop. I have tried a new fuse in it, but the switch on the cable was sparking and the lightbulb was not coming on. It is not a fault with the lightbulb as it's working fine in other lamps. If anyone with electrical knowledge knows how to fix this, they are more than welcome to have this lamp for free. Collection from Granton EH51GG, or I can meet you at a local supermarket.
