The frontrunner to become Keir Starmer's Labour deputy accused him of trying to 'out-Reform Reform' and demanded he veer to the left ahead of the local elections next year.Lucy Powell, who was in Sir Keir's Cabinet until earlier this month, hit out as she campaigned for the senior party post vacated by Angela Rayner. In a thinly veiled jibe at tougher immigration policies championed by Sir Keir and new Home Secretary Shabana Mahmood she warned that aping Nigel Farage's party 'is not going to help us'.She said the party had to rebuild its 'voter coalition', pointing out it was also losing voters to its left.The Manchester Central MP told a hustings at the party's conference: 'Being tactical about it and trying to out-Reform Reform is not going to help us in those elections next May.'And that's what I've been saying this week, we've got to seize back the political megaphone in this country, because let's be honest, we've ceded it too long in recent months.'In answer to a later question about Labour's chances in next year's elections for the Welsh Senedd, Ms Powell warned that Labour's voter coalition was 'fracturing' across the UK.And even challenger Bridget Phillipson, who as Education Secretary is seen as the leadership's choice to become deputy leader, warned against trying to 'ape' Reform. Lucy Powell, who was in Sir Keir's Cabinet until earlier this month, hit out as she campaigned for the senior party post vacated by Angela Rayner. In a thinly veiled jibe at tougher immigration policies championed by Sir Keir and new Home Secretary Shabana Mahmood she warned that aping Nigel Farage's party 'is not going to help us'.Ms Powell said Sir Keir's Government had introduced policies - such as the cut to winter fuel payments - that 'don't show whose side we are on', as she urged action to stop Labour 'losing votes to all sides'.Ahead of the 'difficult elections' in Wales next May, Ms Powell said: 'What we're seeing in Wales is a real example of what we're seeing elsewhere, which is the fracturing of our voter coalition, the fracturing of the electorate.'Yes we're losing some support to Reform, but we're actually losing much more support to Plaid Cymru in Wales at the moment.'That's why we need to reunite our voter coalition with that really strong, compelling story about what we think is really wrong with this country and how we're going to fix it.'We've got to accept that we can do better, we've got to do better.'Because when we bring in policies that don't show whose side we are on and people aren't really clear about whose side we are on - like the winter fuel payment, for example - that hits us particularly hard in our traditional Labour areas, of which there are many across Wales.'So we've change the policy on the winter fuel, but I don't people know about that, so we need to be out there telling people what we are doing.'But we've got to get the politics of this right so that we're not losing votes to all sides.'I don't write off those elections next year, absolutely not. I think we're in the fight of our lives, we can turn this around.'She hailed Sir Keir's conference speech yesterday, in which he launched a series of attacks on Nigel Farage, for beginning to 'wrestle back the political megaphone in this country and set the terms of the debate ourselves'. While Sir Keir is locked in a racism row with Mr Farage over Reform's plan to deport people with indefinite leave to remain (ILR) in the UK, the PM and Ms Mahmood have set out Labour's own clampdown on immigration.Sir Keir said the Government will revisit how international law is interpreted as it addresses the challenge of mass migration.The Prime Minister said the way UK courts interpret international laws such as the European Convention on Human Rights needs to be re-examined.'We need to look again at the interpretation of some of these provisions, not tear them down,' he told the BBC.The remarks were made in the wake of the Home Secretary's speech, in which she detailed plans to tighten the rules for migrants seeking ILR, a status allowing legal migrants to settle in the UK without visa renewal.Under the proposed changes, migrants would need to demonstrate they are contributing to society, including speaking English to a high standard and maintaining a clean criminal record in order to qualify for permanent residency in the UK.Challenger Bridget Phillipson said Labour was 'in the fight of our lives' against Reform.'We can't ape them, we have to take them on in a way that is consistent with our values, Labour values, that are also the values of the British people,' the Education Secretary said.'We're an outward, compassionate country where our diversity is our strength.'
