Tony Blair has been told by a Birmingham MP that he is not doing enough to help former Rover workers.
Labour MP Richard Burden, whose Northfield constituency includes Longbridge, issued the blunt warning in the House of Commons.
The Prime Minister pledged to make sure sacked workers received help, but made no specific promises of any extra aid.
More than 3,000 people who either worked for Rover or for the car giant's suppliers had already been found new jobs, he said.
Speaking in the Commons, Mr Burden praised the work of the Rover Task Force, a body which includes Government agencies, MPs and the city council, which had helped local businesses and workers.
But Mr Burden said: "I would ask him to recognise that there are still a large number of people without jobs, mainly concentrated in the area around the plant, and we still face real problems there.
"South-west Birmingham needs a major regeneration programme."
Mr Blair said: "The way the different agencies have pulled together has been remarkable and 3,000 people have been found new jobs. However, we have got to do a lot more."
The Government would continue to put funding into Advantage West Midlands, the regional development agency, to help the region, he said.
A total of 3,011 workers have been been found jobs with the help of the MG Rover Taskforce.
According to the taskforce, almost all the remaining Rover workers have been found training courses.
But unions have warned that less than a third of people who lost their jobs when MG Rover collapsed have found work - and some of these were forced to take positions paying only a third of their old wages.
A survey by the Amicus union of its 2,000 members who worked at the car plant found that 28 per cent of them have found work since the closure, and only 15 per cent are back working in manufacturing.
Another 11 per cent are training for new work.
The problem is worse for the over-50s, who made up a large proportion of MG Rover's workforce, with many employees having worked at the carmaker all their lives.
The Rover Task Force has estimated that the jobs toll from the closure will be 13,000, after knock-on losses in automotive supply companies.
