An 18-year-old student has achieved four A* at A-level while acting as full-time carer to his disabled mother.

Robin Denham, from Shoreham, achieved his results in Spanish, Chinese, maths and further maths at Brighton College and will go on to study modern languages at Corpus Christi, Cambridge.

He moved to Sussex with mother Rosie, 52, who has Ehlers-Danlos syndrome, from near Carmarthen in south-west Wales, specifically to study at the independent school.

Mr Denham said: "It's still a bit of a shock, I am proud, considering what has been going on in exam season it's pretty incredible."

The teenager has been the sole carer for his mother, who is confined to a wheelchair, since his father died when he was nine years old.

He said: "To other people it seems like a lot to do but for me it's the normal."

His mother added: "I am incredibly proud, it's not been an easy ride."

Mr Denham, who wants to become an interpreter, said: "Working for the EU would be interesting but not sure how that would go now."
