Coronation Street, David Platt is left horrified when Callum Logan steps up their battles over Max, making it clear that he is no longer prepared to be reasonable.

When David arrives back home and finds Callum with Sarah, the bad boy covers by making out that he only called in to see Max.

As the rivalry between the two men escalates, Callum goes in for the kill by telling David that he won't be attending their mediation sessions anymore and will instead see him in court. How will David react?
