From the BBC:
A senior minister is ready to quit over concerns about Gordon Brown's leadership, the BBC has learned.The obvious question we will all be asking is, who is it? Seeing as they have spoken to the BBC, it won't be long before the break cover, or it gets leaked. I'm hoping it's Liam Byrne.
The unnamed minister of state said he believed the prime minister had failed to show the vision needed to lead the Labour Party.
He said he did not believe Mr Brown was the man to "lead us to victory" and he could not continue to lie about it.
It comes as former cabinet minister Margaret Beckett warned Labour rebels to get behind Mr Brown.
The former deputy leader said voters would neither "understand nor forgive" the party if they focused on internal rows.
But speculation continues over Mr Brown's future with an unnamed cabinet minister now threatening to resign.
He told the BBC: "There just comes a point where you say, 'I can't go on lying', you can't go on saying 'I think Gordon Brown is the man to lead us to victory' when you don't believe it."
