Last month, the Government published its findings following the consultation on whether to devolve the power to extend Sunday trading hours to local areas.
Today, a handful of ministers announced that they are ready to block the plans unless they are watered down before a Commons vote this week.
The proposal to extend Sunday trading hours, announced by George Osborne last year, represents the biggest overhaul of Sunday trading laws in 20 years.
The government may be forced to amend its plans to relax Sunday trading rules after Tory MPs threatened to vote down the measure. Ministers, some of their aides and dozens of backbenchers are ready to block the plans unless they are altered before a Commons vote this week, according to the MP leading the rebellion.
