The Downing Street officer accused of lying by Andrew Mitchell has released a statement through the Police Federation saying he stands by his statement.
PC Toby Rowland said:
I stand by my account of events in Downing Street on 19th September 2012.
This has now been thoroughly investigated and the CPS has confirmed there is insufficient evidence to take any criminal proceedings against me.
In addition, neither am I subject to any disciplinary proceedings.
I confirm that I am prepared to give evidence under oath if required.
Andrew Mitchell says he has been "stitched-up" by police whilst one officer was charged with misconduct in relation to the ongoing scandal.
Today's charges come more than a year after the events that led to the end of Mr Mitchell's career. Here is what has happened since.
