The union Unite has called on the Tory party to come clean about 'links' to payday loan companies after Wonga recruited a senior prime ministerial advisor on digital strategy.
The appointment of Jonathan Luff, David Cameron's former digital strategy chief, as head of Wonga's government affairs team follows previous allegations of close ties between prominent payday lending industry figures and the Tory party.
“This appointment raises further serious questions about the relationship between senior Tory party figures and the legal loan sharking industry," said Len McCluskey, Unite general secretary.
The Daily Telegraph claimed this month that Conservative ministers agreed to hold meetings with Wonga in exchange for payments to the party.
Earlier in October, Wonga agreed a four-year sponsorship deal with football club Newcastle United, prompting an angry reaction from local politicians who labelled the company "irresponsible".
