Early contests in the race to be Labour's deputy leader are exposing divisions within the party and creating headaches for the government as candidates rush to secure the 80 MP endorsements needed to proceed.
With nominations due in a matter of days, several contenders have begun public activity. Education Secretary Bridget Phillipson, who has already accumulated roughly 44 MP backers, spoke to trade unionists at the TUC Congress in Brighton without mentioning the contest. Lucy Powell has reported about 35 endorsements. Other declared candidates remain in single figures, and hundreds of Labour MPs have yet to declare for anyone, Labour figures show.
The speed required to reach the nomination threshold is concentrating campaigning on rapid outreach to colleagues, often in parliamentary tearooms, and on filling spreadsheets of potential supporters. The crowded early stage has produced sharp lines of division between those who serve in government and are constrained by collective responsibility and those on the back benches who can be more openly critical.
Emily Thornberry, a former member of Sir Keir Starmer's shadow cabinet who did not receive a ministerial post after Labour won the general election, has positioned herself as a more outspoken candidate. In a social media post she said, "We've made mistakes and must listen. Welfare. Gaza. Wealth tax," adding that she would not "just nod along." The remark was widely read as signalling a willingness to challenge government policy from within party leadership.
Bell Ribeiro-Addy, a left-wing backbencher, has used interviews to criticise the nomination process and the government. Her demands include rescinding the two-child benefit cap, imposing a full arms embargo and sanctions on Israel, and removing the ban on the activist group Palestine Action. Ribeiro-Addy has also complained publicly that the short timeframe for gathering nominations is undemocratic and may curtail broader participation in the contest.
The presence of high-profile government ministers among the declared candidates, including Phillipson and fellow minister Alison McGovern, creates a strategic choice for MPs and party members. If multiple non-ministerial candidates clear the first hurdle, the contest could develop into a forum for critics of current government policy to gain a national platform during a sensitive period for the administration.
Political strategists and officials in and around Downing Street have privately expressed concern that a deputy leader not bound by cabinet discipline could amplify internal criticism in the run-up to key fiscal and policy moments, including the November Budget. Labour sources say the make-up of those who pass the initial 80-MP test will be decisive in shaping the tone of the campaign.
Party officials are overseeing the short timetable for nominations and endorsements. Candidates have described intense, day-to-day outreach to colleagues and supporters to reach the required numbers. For some hopefuls, the campaign may last only days if they cannot secure the necessary backing.
As the race progresses, the immediate questions are which candidates will clear the nomination threshold and how many of those advancing will be free to criticise the government publicly. The answer will determine whether the deputy leadership fight remains a contained internal selection or turns into a broader debate over Labour policy and direction ahead of the autumn parliamentary agenda.
