The leader of Harrow’s Conservative group has described a councillor's possession of indecent images as “shocking and deeply disturbing”.

Councillor Susan Hall has reacted to the news that Harrow Borough Council’s former cabinet member for children, schools and families has been cautioned for possession of indecent images of children and placed on the Sex Offenders Register for two years.

She said: “This is shocking and deeply disturbing news. Given Councillor Gate’s previous position as portfolio holder for children’s services and schools, it is vital that all appropriate enquiries and safeguarding investigations take place.

“In addition, as Cllr Gate has accepted a caution some five months after his arrest, residents are entitled to know whether he continued to accept his allowance as a councillor in the intervening period.

“Trust is paramount to the relationship residents should have with their councillors, and the criminal acts of this Labour councillor amount to some of the most appalling breaches of trust anyone can imagine.

“Though he has resigned, Cllr Gate’s despicable actions have sent shockwaves through Harrow Council. I’m truly disgusted by his actions, and I’m sure Harrow residents are too.”

Mr Gate, 58, who was the West Harrow representative, was arrested at his Harrow home on September 24, 2012, on suspicion of possession of indecent images of children.

He was bailed pending further inquiries and was cautioned and placed on the Sex Offenders Register on Monday.

He has resigned from his position at the council and also from his governorship of St Dominic’s College.
