HUNDREDS of thousands of public sector workers will take part in a national strike on June 30, two teaching unions confirmed today.

Millions of pupils at thousands of schools across England and Wales are expected to be affected as members of the National Union of Teachers (NUT) and the Association of Teachers and Lecturers (ATL) stage a walkout in their bitter row over pensions.

The announcement comes ahead of an expected decision by the Public and Commercial Services union (PCS), due later this afternoon, that up to 250,000 of its civil service members will also strike on the same day.
