The female tech entrepreneur at the centre of a brewing political scandal involving prime minister Boris Johnson was paid "low five-figures" by ITV's Good Morning Britain to appear on the show on Monday, according to a source familiar with the matter.

Jennifer Arcuri gave her first TV interview to Good Morning Britain after three weeks of stories in the British press about her close relationship with Boris Johnson and allegations of conflicts of interest during his time as London mayor.

A series of Sunday Times reports over several weeks have detailed Arcuri's close relationship with Johnson, with both refusing to deny they were also having an affair. There are also now four separate inquiries into Johnson's conduct as mayor and public grants given to Arcuri.
