A Liverpool dad is taking to the streets of the city for 12 hours today campaigning to get defibrillators in schools after his son died at school from sudden cardiac arrest.
Oliver was suffering from undiagnosed sudden arrhythmic death syndrome (SADS), 12 young people die per week in similar cases.
Oliver's father Mark set up the Oliver King Foundation in his name, to raise awareness of SADS and are campaigning to provide screening for the condition and defibrillators in schools.
He and Cllr Jake Morrison have set up an e-petition to get the issue debated in parliament. Campaigners still need over 50,000 signatures.
