Sparks bring Park Lane to a standstill.

Electricians brought London’s exclusive Park lane to a standstill last night as they protested outside the annual ECA Dinner Ball at the exclusive Grosvenor House Hotel. For over an hour one of London’s busiest roads was blocked as the sparks and their supporters took the fight to the bosses. Ken Livingston spoke during the protest and pledged that companies who tear up agreements will not find work on London Underground if he is elected.
