Lower Marsh was filled with spaceships and aliens on Friday for this year's Waterloo Carnival.
The centrepiece of the all-day event was the lunchtime carnival procession involving more than 300 local people of all ages.
The procession started at Johanna Primary School and travelled via Lower Marsh, Westminster Bridge Road, Baylis Road and the Tanswell Estate to reach Waterloo Millennium Green where Kate Hoey MP welcomed all the participants and spectators.
As well as pupils from Johanna and two other Lambeth schools, the procession also included members of Waterloo Parents' and Carers' Network, Coin Street nursery and Blackfriars Settlement seniors' group.
This year's event was staged by the Friends of Waterloo Carnival, a new group set up to safeguard the future of this popular summer event, with backing from Waterloo Quarter BID, Bankside Open Spaces Trust and others.
