Campaigners have called for controversial anti-terrorism powers to be scrapped after a new report found they may be "withering on the vine" and need to be reviewed.

The call follows the publication yesterday of a study into the government's terrorism prevention and investigation measures (Tpims) by the joint committee on human rights.

Tpim subjects face restrictions including overnight residence at a specified address, tagging, reporting requirements and restrictions on travel, movement, association, communication, finances, work and study.
