St Helens MP Conor McGinn has thrown his support behind sacked shadow foreign secretary Hilary Benn.
Mr McGinn, who was elected as Labour MP in May last year, saluted Mr Benn’s work during the EU referendum, and called him “a man who loves and cares deeply about the Labour Party and his country”.
But his tweet prompted a series of vitriolic attacks from dozens of Labour leader Jeremy Corbyn’s supporters, with one branding both McGinn and Benn “warmongers”, a reference to their support for the Syrian bombing campaign.
Mr Benn was dimissed in the early hours of Sunday morning after he told Mr Corbyn he had lost confidence in his leadership.
This triggered a series of resignations, including Mr McGinn’s friend and former boss Vernon Coaker, with over 15 members of the shadow cabinet walking out.
It is widely known that Mr McGinn is no fan of Mr Corbyn’s leadership, and his support for Mr Benn is his most public declaration to date of that dissatisfaction.
He wrote: “It was a privilege to campaign beside @hilarybennmp during the #EURef. A man who loves & cares deeply about the Labour Party & his country.”
The 31-year-old currently serves as an opposition whip.
It’s unclear whether he will continue in the role under Mr Corbyn’s leadership.
His messages was retweeted 53 times and liked 63 but prompted a series of angry responses from Corbynists.
