Chancellor George Osborne’s plan to change Sunday trading laws gains a lot of traction in all the papers this morning.

The Guardian says the chancellor will allow local authorities and mayors to decide how long large stores can stay open on Sundays, ending national six-hour limit. It would be the biggest shakeup of trading laws since the reforms of the 1990s. Osborne was ready for a fight with religious leaders and unions as he prepares to deliver tomorrow’s Budget, according to The Times. The offer to rip up the remaining restrictions would delight big retailers but antagonise corner shops and the religious right, The Financial Times adds. Osborne said there was a “growing appetite for shopping on a Sunday” and that businesses needed the change to ensure that they could compete with online retailers (The Telegraph).
