CORONATION Street boss Iain MacLeod has revealed Oliver Battersby will be diagnosed with Mitochondrial disorder. The toddler's parents Leanne Battersby and Steve McDonald - who are played by actors Jane Danson and Simon Gregson in the ITV soap - will be left devastated by the diagnosis.
Viewers have seen Oliver suffer a series of seizures over recent weeks and he has been clearly unwell over the last few months, but until now his parents had no idea how serious his illness was.
In the months to come Leanne and Steve will be forced to come to terms with the heartbreaking diagnosis which will leave Oliver with a life limiting illness for which there is currently no cure.
