Professor Cantor claimed £135,000 over three years
The University of York's vice-chancellor claimed more than £50,000 in expenses last year it has emerged.
The amount claimed by Professor Brian Cantor was almost double the sum claimed by his counterpart at Oxford University.
The figures were revealed after a Freedom of Information request by student newspaper York Vision.
The university said the claims related to activities which were "essential" to maintain its "global standing".
Prof Cantor claimed £134,857 in expenses over the last three years, including £50,542 last year alone.
Travel expenses, including plane tickets, accounted for £69,842 of the claims over the three years.
'Approved' by treasurer
Prof Cantor declined to comment but a university statement said: "York is ranked 70th out of a total of nearly 30,000 universities in the world.
"Regular international travel is an essential part of maintaining and developing that global standing, and the vice-chancellor's drive to establish and nurture international partnerships has played a significant role in achieving it.
"All the vice-chancellor's expenses are approved by the university treasurer and, along with the expenses of other senior staff, are reported to remuneration committee."
York Vision compared Prof Cantor's expenses to the £26,957 claimed over the same period by the vice-chancellor of Oxford University, Professor Andrew Hamilton.
York University has an income of £225m, educates 12,000 students and employs 3,000 staff.
The deputy vice-chancellor and the six pro-vice-chancellors claimed a total of £92,225 over three years.
