Cycle lane often blocked by buses and other vehicles

The junction at the end of London Road has a painted-on cycle lane which filters between lanes of traffic. When there's a bus at Bus Stop E (which is frequent, given it serves 10 different routes), left-turning vehicles go round the bus and then have to cross the cycle lane to get to their left-turn lane. Given how close this is to the traffic lights, this means there's often a vehicle blocking the cycle lane while waiting at a red light. A lot of great work has happened to improve the cycle infrastructure in and around Elephant & Castle. So I'm always surprised that this particular part has been left so dangerous.
