Olympic events are expected to cause some delays across various parts of London today.

The women's marathon is causing delays, with slow traffic on A100 Tower Bridge in both directions in City Of London between the A200 Queen Elizabeth Street junction and the A1203 junction.

Some roads have also been closed for the event, which is expected to affect traffic from around 11am to 2pm.

Traffic is also expected to be busy around Wimbledon from approximately 1pm, with Andy Murray scheduled to start his singles final against Roger Federer at 2pm. The Scot will then be joined on court by Laura Robson for their mixed doubles final against Victoria Azarenka and Maxim Mirny of Belarus.

There are currently no major line disruptions on the London Underground, though they are likely to get busy for the evening's events, so travellers are advised to leave plenty of time as they make their way to the venues.

Tonight's men's 100m final will ensure a full house at the Olympic Stadium, so traffic around the venue is expected to cause delays.
