Keith Davies: Labour Llanelli AM 'in stable condition'
The Labour Party has said Llanelli AM Keith Davies is in a stable condition after a fifth night in hospital.
The 71-year-old was admitted to the University Hospital of Wales, Cardiff, on Wednesday.
Welsh Labour said on Monday that he was still undergoing tests at the hospital's neurosurgical unit.
He attended a function organised by a public affairs group before being admitted, but party officials say it is not clear how he fell ill.
A party spokesman said: "Keith Davies is in a stable condition at University Hospital of Wales. He is still undergoing tests at the neurosurgical unit and remains under observation.
"Keith's family and Welsh Labour would like to thank those who have sent messages of goodwill and support."
He was first elected to the assembly in May last year at the age of 70, taking back Llanelli for the Labour Party from Plaid Cymru by 80 votes.
Well-wishers from across the political spectrum have sent messages of support.
