Labour's climate envoy has been accused of living like a 'travel writer' after it emerged she has effectively circled the globe three times in her new role.

Rachel Kyte has clocked up more than 75,000 air miles since her appointment in September – costing taxpayers almost £40,000.

The majority of her flights were in business class, according to details released to The Telegraph via a Freedom of Information request.

Ms Kyte, an academic and fan of environmental group Extinction Rebellion, was recruited by Ed Miliband in September as the UK's new 'special representative for climate'.

She has previously admitted her carbon footprint was 'a source of deep discomfort', but she visited a foreign country every month between October and May.
