SIR – Garry Lorriman’s recent attack on Diane Abbott MP (Letters, October 20) when he refers to her as having an IQ in single figures is just another example of his political bias.

Ms Abbott is the daughter of West Indian working class immigrant parents and yet in spite of her disadvantaged background and “single figure IQ” still managed to achieve a Cambridge MA in History.

How about you, Mr Lorriman?
