City law firm Rosenblatt is said to be considering an IPO. The firm with revenues of around £16m has not confirmed or denied the reports, according to City AM. If it took such a step, the firm would be the fourth law firm to float in the UK - Gateley, Gordon Dadds and Keystone Law have already gone down this path.  According to City AM, founder Ian Rosenblatt would neither confirm nor deny that the firm was contemplating a float, saying that: 'I’m mulling what suit to wear tomorrow too.'
