Police probe 'multiple allegations' against Angela Rayner: Dozens of officers ... trends now Police investigating Angela Rayner's housing arrangements are probing multiple allegations and are not just looking at whether she broke electoral law, it emerged tonight. Dozens of Greater Manchester Police officers are investigating the Labour deputy leader after Tory allegations that she may have given false information about her main residence in the 2010s. Ms Rayner, 44, has promised to resign if she is found to have committed a crime over the accusations, but said she 'followed the rules at all times'. The under-fire MP is being investigated over claims she wrongly declared on the electoral roll she was living at a council house she bought under right to buy, on Vicarage Road, Stockport - when it is claimed she was living primarily at her husband Mark's home a mile away in Lowndes Lane. But The Times reports that police are also investigating 'tax matters and other issues' in connection with her housing affairs. Ms Rayner (pictured on Tuesday), 44, has promised to resign if she is found to have committed a crime over the accusations, but said she 'followed the rules at all times' The address on Lowndes Lane - around a mile from Ms Rayner's property on Vicarage Road, which she insisted was her home A source told the newspaper: 'It's very well resourced, it's not a single issue. There is a volume of material and a clear public interest to fully investigate.' The bombshell update in the investigation comes just weeks ahead of the local elections next month. Chief Constable Stephen Watson told local radio on Tuesday that 'there are a number of assertions knocking about' and 'we are going to get to the bottom of what has happened.' Rayner maintains that she took expert legal and tax advice and was confident everything was done by the book. Labour leader Sir Keir Starmer has backed Ms Rayner but said he does not need to see the advice. Under electoral law, parliamentary candidates must be registered to vote at their permanent address. The Labour deputy has tried to put the weeks-long row behind her, going about business as usual on Tuesday when she attended a housing development in West Sussex to meet families struggling to get mortgages with shadow chancellor Rachel Reeves. The council house row escalated on Friday when GMP said it was launching a formal investigation. It came after James Daly, the Tory deputy chairman, complained that officers had not contacted witnesses, looked at the electoral roll or other relevant documents. Over the weekend, The Sunday Times revealed that a former aide had given a statement to GMP which contradicted her claim that her primary residence for five years was away from her husband and three children. Rayner has also faced questions over whether she should have paid capital gains tax on the council house when it was sold in 2015 for a £48,500 profit, if it was not her principal residence. Neighbours also claimed that her brother lived at the property and Rayner had described herself as the 'landlord'. The Labour Party pointed MailOnline to Rayner's statement on Friday. Rayner said: 'I've repeatedly said I would welcome the chance to sit down with the appropriate authorities, including the police and HMRC, to set out the facts and draw a line under this matter. I am completely confident I've followed the rules at all times. The Labour deputy has tried to put the weeks-long row behind her, going about business as usual on Tuesday when she attended a housing development in West Sussex to meet families struggling to get mortgages with shadow chancellor Rachel Reeves Labour leader Sir Keir Starmer has backed Ms Rayner 'I have always said that integrity and accountability are important in politics. That's why it's important that this is urgently looked at, independently and without political interference. 'I make no apologies for having held Conservative ministers to account in the past. Indeed, the public would rightly expect me to do so as a Deputy Leader of the Opposition. 'We have seen the Tory Party use this playbook before – reporting political opponents to the police during election campaigns to distract from their record. I will say as I did before - if I committed a criminal offence, I would of course do the right thing and step down. The British public deserves politicians who know the rules apply to them. 'The questions raised relate to a time before I was an MP and I have set out my family's circumstances and taken expert tax and legal advice. I look forward to setting out the facts with the relevant authorities at the earliest opportunity.' MailOnline has contacted GMP for comment.
