Walkers pulled the plug on its new advert yesterday hours after construction union Ucatt branded it insensitive and offensive for a “joke” resembling a fatal accident being probed this week.

The union hit out angrily at the planned the TV commercial, which saw ex-England footballer Gary Lineker having wet concrete poured onto him from a great height for refusing to share his crisps.

It aired during peak hours on Monday night — on the same day an inquest began into the death of 44-year-old father Rene Tkacik.
