Hayley Child from Lincolnshire County Council came up with the idea of a codeword for people to use when they are in vulnerable or uncomfortable situations.

The 'Ask for Angela' campaign enables people who are feeling unsafe while on a date to alert bar staff, who can defuse the situation or arrange a taxi.

A photograph of one of the 'Ask for Angela' posters recently went viral on Twitter, leading to calls for the campaign to spread beyond Lincolnshire bars.

Tom Barton went to the Strait and Narrow bar in Lincoln to see how it worked.
