Road cones, shopping trolleys, even a bath tub - they have all been found on the bed of London's Regent's Canal.

It is the first of a number of canals in England and Wales to be drained ahead of vital restoration work.

It is a huge task that has involved draining the equivalent of 14 Olympic swimming pools.

BBC reporter Tim Muffett sent us this report.
