Alastair Cook shrugged off calls from Kevin Pietersen to resign as England captain ahead of the third Test against India at Southampton.

The former England star used his Daily Telegraph column published on Saturday to say Cook was only still in the job because it would be "yet another PR disaster" for the England and Wales Cricket Board to sack him now.

Cook has faced repeated calls to resign the captaincy from the likes of Michael Vaughan and Nasser Hussain during a run that has seen England go 10 Tests without a win.
