'It requires little effort and no sacrifice'

Some like campaigning with a status update on Facebook, changing a profile picture on twitter, wearing a wristband or sporting a badge with a catchy slogan.

Journalist James Bartholomew is not convinced this approach achieves much, as he looks at what he calls 'virtue signalling' in a personal film from Octavia Hill's Birthplace House in Wisbech.

On Wednesday's Daily Politics, he will debate this film with MPs Therese Coffey and Jack Dromey around 12:40 GMT.
