Carol Howard, 39, is alleged to have called her ex-husband 'tight, white Scottish trash'

A former Met police poster girl who is suing the police watchdog over claims of institutional racism has been accused of sending a racist text.

Carol Howard, 39, is alleged to have called her ex-husband 'tight, white Scottish trash'.

The text was discovered after she was arrested three times for ABH between August 2013 and April 2014.

No action was taken over the arrest and it is believed bosses 'covered up' the crimes.

Last month, Ms Howard was hailed as a whistleblower when she took the the Independent Police and Crime Commission to employment tribunal accusing it of being 'institutionally racist and corrupt'.

She is seeking £144,000 in compensation from for racial discrimination in an ongoing tribunal.

Ms Howard previously took the police to a tribunal and won £37,000 on the ground of sexual and racial discrimination, accusing her boss of being 'vindictive and spiteful' toward her.

But now lawyers acting for her then-boss David Kelly are demanding the Met explain why the text was never disclosed, arguing that her 'apparently racist views of white people' mean her comments about Mr Kelly should be disregarded.

There are further claims that the Deputy Met Commissioner Craig Mackey knew of the text but it was 'kept quiet', according to the Sun of Sunday.

Her solicitor said of the text was 'repeating to him his description of himself.'

Last week, she told an employment tribunal that the watchdog frustrated inquiries in order to protect accused officers and the reputation of forces.

Ms Howard is a former firearms officer, who famously appeared as a Scotland Yard poster girl - complete with Heckler & Koch semi-automatic rifle - promoting efforts to protect London during the 2012 Olympics.

The Met quit the Met in 2015 after 14 years experience in the police force.

She won a £37,000 tribunal payout in a high-profile race discrimination case and went on to join the IPCC as an investigator the following year.

Ms Howard, of Coulsdon, Surrey, is now seeking a further £144,000 payout for alleged racial discrimination and victimisation during her six-month stint at the IPCC.

She told Central London Employment Tribunal that the IPCC, while probing misconduct and racism, was itself riddled with corruption and discriminatory practices.

She alleged that some IPCC investigators secretly supported the racist police officers whom they were investigating.
