As temperatures reached over 30 degrees Celsius inside the poorly cooled new Routemaster replacement buses, Caroline Pidgeon told the Evening Standard:
"After spending a fortune of public money and after extensive testing the public should not have to put up with a cauldron on wheels.
"The Mayor and TfL should stop making excuses and ensure that such basic problems are sorted out as a matter of urgency."
Following the tragic death of a cyclist on Cycle Superhighway 2 at Aldgate East, Caroline Pidgeon told the BBC that the initial superhighways are flawed as they are "little more than blue paint put down on the road".
Caroline added: "London needs to rapidly learn from practices in Denmark and Holland and ensure we have widespread segregated cycling lanes and junctions that are safe for all road users."
Caroline Pidgeon told the BBC's Tom Edwards - after learning that passengers on some of the Mayor's new "Routemaster replacements" will not be able to get on and off the bus between stops:
Southwark Liberal Democrats’ campaign for new schools in the borough was given a boost this week with a visit from the Minister for Schools, David Laws MP.
The Liberal Democrat minister met parents and local councillors in East Dulwich to discuss the shortage of school places in Southwark and what the Government is doing to support new schools.
Looking back at 10 years of Oyster, and its uncertain future as "wave and pay" technology is introduced, Caroline Pidgeon told the Mayorwatch website:
"While wave and way technology will inevitably become more widespread over the next few years there can be no excuse for people using Oyster who have no access to a bank account being penalised.
"The Mayor must honour his specific pledge that Oyster fares will remain the cheapest fares. If a weekly cap is introduced on using wave and pay on London buses then it is vital that a similar cap applies on Oyster PAYG weekly fares."
