I have macbook 15 ince retina 2013 late and i bought it from the UK, after i moved to Jordan i faced a problem when i charge my mac i got electricized,, so every time i touch the case of the macbook i feel the electricity until i plugged off the charger from the electricity source. please tell me what to do

if the problem from the macbook itself or the charger what could i do ?

if the problem from the electricity what could i do ? dose the voltage of the electricity in the UK is different from the electricity in Jordan ? so if yes, what is the solution ?

Thank you very much
