First Buses have released details of a raft of changes to bus services in the Norwich area, following heavy criticism of changes brought in during January.

From Sunday, April 1 the changes below will come into effect due to what First have described as 'following recent passenger feedback and the ongoing review of our Norwich Network'.

Nigel Barrett, regional managing director of First South East & Midlands, said: 'We regularly review passenger numbers and the level of service we provide on all of our routes, especially given the current and worsening economic climate.

'We have also had to consider the changes to supported services by the local authority and the loss of 20pc of the Bus Services Operators Grant and the continuing fuel price increases.

'Wherever possible we have tried to offer alternative routes or times and introduced a Sunday service where we think this is commercially viable but we are aware that these alterations may inconvenience some of our passengers, but I can assure you that the decisions were not taken lightly and followed a full and thorough review of all of the affected services.'
