MPs will vote later on whether the UK government broke Parliament's rules by failing to publish the legal advice it received about the Brexit deal.
This latest hurdle is another blow for small firms, according to Craig Beaumont, the director of external affairs and advocacy at the Federation of Small Businesses.
He says the group's members will be looking at the unfolding political drama with increasing unease.
"Confidence has been on a downward track since quarter three and we expect it to accelerate now. If you're a small business why splash out on a new member of staff when you don't know what the economic framework is?", he asks.
He says skill shortages are also causing issues for firms due to a sharp drop in EU migration. "It's a real squeeze at the moment," he says.
