Labour Party arrives in Liverpool for conference
The Labour Party conference is under way in Liverpool and is expected to bring in an estimated £15m to the city's economy over the next five days.
Up to 11,000 visitors and delegates are expected at the event which is being held at the Arena and Convention Centre overlooking the River Mersey.
The venue hosted the Liberal Democrat Party conference in 2010, bringing in about £10m.
The annual conference is scheduled to run until Thursday.
There are expected to be about 500 fringe meetings around the city with debates and discussions planned for smaller venues.
There should not be any disruption to public roads throughout the city centre, police said.
Liverpool City Council leader Joe Anderson said: "This is fantastic news for Liverpool, as it clearly demonstrates we are able to handle one of the biggest conferences in the country.
"It is a great opportunity for us to showcase all that is good about the city and how Liverpool has been transformed in recent years."
