The westbound carriageway of the A4 Piccadilly in central London is closed due to an oil spillage, with long delays and queueing traffic.
The closure runs from St James’s Street to Green Park, with congestion reaching Pall Mall and heavier traffic up Regent Street.
This is a developing story — live updates will appear below as they come in.
Piccadilly is one of central London’s main westbound routes, so a closure here quickly backs traffic up onto surrounding streets — Pall Mall to the south and Regent Street to the north are both feeling the effects.
What is not yet known: what caused the spillage, whether any vehicle was involved, and when the road will reopen. The road will stay closed while the spillage is dealt with, and this article will be updated when officials confirm a reopening time.
Drivers heading west through central London should expect delays and consider avoiding the Piccadilly stretch until it reopens. Other recent road closures in the capital include a crash that closed the A315 London Road in Hounslow and delays to the 213 bus in Sutton.
