An error by the Health Service Executive has led to close to 20 new medical graduates having their job offers rescinded.

The mistake could also lead to many others being given different employment offers than they were originally notified of.

The problem relates to over 560 general medical intern post offers, for which there were 1,100 applicants from new medical graduates.

The HSE says that all of the affected graduates have been notified of the situation by text and email.

It says that most of the doctors will not be affected, but up to 20 were offered jobs in error.

Because the system will now have to be adjusted, the executive says that some of those who applied for the 560 posts and received offers may now be offered a different hospital location than what they were originally offered.

The final offers are to be issued next week.
