A cut in the drink-drive limit would "decimate" early evening trade and lead to further pub closures, according to a leading regional brewer.
Oliver Robinson, commercial director at Stockport-based brewer Frederic Robinson, told The Publican he is concerned about proposals to cut the limit from 80mg to 50mg of alcohol per 100ml of blood.
He said this would not tackle drink-driving but could seriously damage "early doors trade".
"I often, on my way home, go to a pub and have a pint and chat to the licensee. Just the one pint," he said. "And there are always lots of people in there doing the same. They will not do that any more if the limit is cut and that is important trade for pubs."
The cut - which would bring the UK in-line with many other European countries - was proposed by Sir Peter North QC in a government-commissioned report which is being considered as part of an MP-led inquiry into the current laws.
North claims a cut would save lives, but Robinson refuted this saying there was no firm evidence this was the case
"Nobody condones drink driving, but show me the evidence that a reduction in the limit will save lives. I don't see any statistics that prove a reduction in the limit will help."
He added: "The very small minority of people who do drink and drive are going to continue to drink whatever the limit so a cut isn't going to stop them."
Robinson's comments echo those of the BII, which has also responded to the inquiry saying any cut in the limit would lead to more pub closures and cause confusion among drivers.
Reports last month suggested the Transport Secretary, Philip Hammond, is not keen on reducing the limit and will reject North's recommendations.
