Economy Minister Edwina Hart has now issued a statement confirming that she's stepping down as an AM at next year's Assembly election.
Together with Finance Minister Jane Hutt, Edwina Hart is one of just two AMs to have been in the Welsh Cabinet since it was first formed under Alun Michael in 1999. She contested the Welsh Labour leadership when Rhodri Morgan stood down as First Minister but was defeated by Carwyn Jones.
Two of Edwina Hart's constituency neighbours have also announced today that they're standing down. Gwenda Thomas also confirmed her decision to her local party in Neath this evening, with Keith Davies earlier making his announcement in Llanelli.
One of the two Assembly members to have served in every Welsh cabinet since the first election in 1999 is expected to announce tonight that she won't stand again next year. Economy and Transport Minister Edwina Hart is understood to be making the announcement to her Gower constituency party this evening.
The former Deputy Health Minister Gwenda Thomas is also due to tell her local party in Neath tonight that she too won't be seeking re-election. They join Keith Davies who announced earlier today that he will be quitting Llanelli after just one term as an AM.
So three Labour AMs in neighbouring seats are all leaving the Assembly next year. But it's Edwina Hart's decision that will command the most attention. One of the most powerful figures in the Welsh Government, responsible over the years for finance, health and now the economy, she'd been tipped as a possible successor to Dame Rosemary Butler as the Assembly's Presiding Officer.
The Labour party encourages its AMs and MPs not to leave it so late to declare their intentions and another five have already done so. Last minute announcements are by no means unusual but by delaying her decision Edwina Hart has left herself open to suggestions that she fears the loss of Gower to the Conservatives, who won the Westminster seat for the first time at the General Election last month.
The Welsh Conservatives are dismissing the latest Labour attack on their spending priorities which Llanelli AM Keith Davies says would have led to nearly 10,000 teachers losing their jobs since 2011. Welsh Tory leader Andrew RT Davies says:
Meanwhile Shadow Education Minister Angela Burns said it's been Labour which has presided over school closures.
Following the news that the Llanelli AM Keith Davies has been discharged from hospital after nearly a month, a spokesman for the Assembly Labour grop said
The Llanelli AM Keith Davies, who has been seriously ill for nearly a month, is said to be recuperating at home after being discharged from the University Hospital of Wales in Cardiff. He'd been diagnosed with a blood clot on the brain. It's understood he was treated without the need for surgery.
Labour have released details on the condition of Llanelli AM Keith Davies who was taken 'seriously ill' last month.
The Welsh Liberal Democrat leader says 'it wouldn't be right' for the parties in the Assembly to take political advantage of the serious illness of Llanelli AM Keith Davies. Kirsty Williams said she understands that Plaid Cymru has made a temporary 'pairing' agreement with the Welsh Government.
Mr Davies' absence leaves Labour without a majority, but the Lib Dem leader said the pairing arrangement is 'appropriate' and that it would be wrong for the other parties to take advantage of the situation.
She also said that she'd sent a text to the First Minister Carwyn Jones when she'd heard about Mr Davies' illness asking him to pass on the best wishes and prayers of her and and her party.
A spokesman for the Labour Party confirms that Keith Davies, the AM for Llanelli, remains in hospital under observation.
