The move is intended to provide greater flexibility for drivers and a boost for local businesses.

The changes follow consultation with Londoners, businesses and boroughs councils, with 19 of the 22 London boroughs affected by the introduction of "Stop and Shop" having welcomed the plans.

Mayor of London Boris Johnson said: ‘Parking is a hot topic for Londoners going about their daily lives, as well as for the Capital’s businesses and retailers. I’m thrilled that we have been able to extend parking time in our high streets. This will make a huge difference to local businesses and I hope everyone will embrace the new "Stop and Shop" bays.’

Sue Terpilowski, London chairman, Federation of Small Businesses, said: 'We welcome the announcement from the Mayor and Transport for London for red routes in the capital to permit 30 minutes of free parking. The Federation of Small Businesses have long argued that parking charges and availability inhibit local spend and 64% of our members say it has a negative impact on their business.

‘This sensible measure will enable more customers to shop locally and enable small businesses to compete with “free to park” out of town shopping centres. We urge Councils in London to think about how their parking decisions impact on the local economy, thus, creating parking policies, strategies and an evidence base which is appropriate in the current economic climate.’
