EAST Lancashire karting star Jonathan Walker will take on former Formula 1 driver Johnny Herbert tomorrow to raise money for charity.

Walker, from Dinckley, races in the KF1 premier class - effectively the Formula 1 of karting - and will relish the challenge against a host of stars in London tomorrow.

The event will raise money for the Warwickshire and Northamptonshire Air Ambulance and Walker, who will race for the Alpinestars team, said: “Johnny’s still quick and considering how successful he’s been throughout his career, you have to respect him.”
