Londoners strip to their underwear for annual 'No Trousers Tube Ride'

Hundreds have joined in an annual group event of travelling on the TfL tube network after removing their trousers and riding in their underwear. It's been an annual event in London for nearly two decades, as passengers ride the Underground with no trousers on - leaving tourists and families totally bemused. But calls are growing for the 'No Trousers Tube Ride' to end amid fears it is causing unnecessary trauma for those who have suffered sexual assaults on the network.
