A new report suggests pregnant women can safely drink a small glass of wine - or 1.5 units of alcohol - every day after the first three months of pregnancy.
The advice is in stark contrast to that which is offered by the Department of Health, which in May advised women to remain teetotal throughout the duration of their pregnancy.
However, according to the National Institute for Health and Clinical Excellence (Nice) there is "no consistent evidence" to suggest that a small amount of alcohol can cause damage to an unborn child.
"The experts have concluded that there is no consistent evidence of adverse effects from low-to-moderate alcohol during pregnancy (less than one drink or 1.5 units per day) but the evidence is probably not strong enough to rule out any risk," a spokesperson for Nice commented.
"The recommendations are subject to consultation and final guidance is due to be published in March 2008."
The experts at Nice have reached their conclusions following a review of existing data.
While it has already been established that heavy drinking during pregnancy can harm an unborn baby, it is unclear as to the effects of more restrained intake.
