Hundreds of students and lecturers gathered outside parliament on the strike day, in protest at cuts to English for Speakers of Other Languages (Esol) provision.
The biggest strike yet under the Tory government was to take place this week. Around 120,000 lecturers were to walk out on Thursday to defend their jobs, pay and pensions.
UCU members were out on strike across Wales today. Union members were on picket lines at Cardiff, Swansea, Aberystwyth and Lampeter universities. They struck as part of a dispute across Britain against attacks on pensions.
