I think it sowed a seed of 'well the government don't actually think its that important to follow the rules', especially when he wasn't punished for doing so. Other plonker politicians from all parties, sportspeople, 'celebrities' and others in the public eye have continued to carry on as if the rules are for other people to observe, reinforcing the same thing. Rita Ora just the other week flew into the country, didn't isolate at all and immediately held a party for a load of friends. I would hope that people don't blindly copy an air headed manufactured pop star, but it sets a climate.
