Labour's pink minibus provokes derision and division

Harriet Harman has been defending the use of a pink van in a Labour campaign aimed at women voters.

Labour's deputy leader said the point "wasn't the colour, but what it stands for", and that it had "attracted women's attention".

While some on social media have criticised the colour, others have described the campaign as "sexist".

At the campaign's first stop in Stevenage, Hertfordshire, a man interrupted the meeting to ask why the campaign was not about men and women.

Meanwhile, during Prime Minister's Questions, David Cameron joked "the wheels are falling off the bus".

The minibus is expected to tour 70 constituencies around the UK.
