A Canadian exchange student who has no degree due to the exams marking boycott fears she may have to leave Scotland.

Emma MacKenzie, 22, has signed a lease on a flat and accepted a full-time job.

But with a deadline of 26 July looming the Edinburgh University English and Art History student cannot renew her visa.

She is one of thousands of students at 145 institutions across the UK who have been affected by the University and College Union's (UCU) boycott.

The union claims the boycott, which began on 20 April, could affect more than half a million graduations this summer.

And it has vowed to continue its action until employers make an improved offer on pay and conditions.

Universities are taking independent decisions about how to minimise the impact, so the effect on students will vary.

Edinburgh University students told BBC Scotland they received empty scrolls with a letter of apology at their graduation on Tuesday.
