Immigration inspectors have discovered more UK Border Agency (UKBA) backlogs totalling over 16,000 cases.
The chief inspector of immigration said the latest backlogs relating to requests to settle through marriage were "unacceptable".
Speaking to Jon Kay on BBC Breakfast, John Vine also said that IT systems that are in place in the UKBA to deal with cases are "outdated".
