A new report has exposed just how high some expenses are for senior staff members at some London universities.
The vice-chancellor at the London School of Economics racked up £60,000 in expenses for premium flights in one year alone.
In a report revealing the spending at universities in the UK, the ones in the capital topped the list.
Some professors claimed up to £34,000.
The University and College Union which is behind the report says it exposes the wild discrepancies in senior pay.
Simon Renton from the union explains more.
An LSE spokesman said: “A key part of the Director’s role at LSE is to maintain an array of international relationships and establish new links with universities, businesses and non-governmental organisations around the world.”
“Inevitably this involves a significant amount of international travel. None of this travel is in first class.”
