Lawyers in England and Wales involved in criminal trials have voted to begin striking indefinitely from next month, the Criminal Bar Association (CBA) said on Monday, threatening more disruptions to court cases in a dispute over government funding.

Barristers in England and Wales have been taking intermittent action for months, refusing to take on new cases or cover cases for colleagues which have overrun. The CBA said almost 80% of voting members had now backed escalating that action. They will now walk out indefinitely from Sept. 5, the day Boris Johnson’s successor as new prime minister is due to be announced.
