A voluntary worker was subjected to repeated racist abuse after a top politician met residents to discuss their concerns at a troubled block of flats.

Susan Jackson had attended the meeting with former Tory leader Iain Duncan Smith to voice concerns about anti-social behaviour at Chartwell Court, Woodford Green.

But neighbour Sarah Oliver-Moth, 42, claimed Ms Jackson was trying to get her thrown out of the housing association block and repeatedly racially abused her.

She is accused of calling her a “black c***” and claimed there was a plot for black people to take over the block.

Prosecutor Sara Gates told the Old Bailey: “The defendant directed a series of comments and nasty racial abuse at Ms Jackson because she was black.”

Youths had been gathering to smoke cannabis and the front door to the building was broken, the court heard.

Ms Jackson was getting out of a cab after work at a local hospital when Oliver-Moth first abused her, it is claimed.

She yelled: “She must be the black b**** that was in the meeting that was trying to get rid of me.”

Oliver-Moth added: “You stupid black b****, I know it was you.”

She appeared slightly drunk and Ms Jackson chose to ignore the incident.

But a week later, on May 17 last year, Oliver-Moth confronted her outside and said: “You want this place to be full of black people.”

“There was a tirade of abuse. Oliver-Moth was aggressive and menacing,” Ms Gates said.

On January 16 this year Oliver-Moth shouted: ‘Here’s that f***ing b**** again.’

She was with a black man and took pictures of Ms Jackson.

The victim was so upset she suffered heart palpitations.

Finally on February 3 Mrs Jackson was walking her dog when she was met with a “similar tirade of abuse”.

Oliver-Moth denies racially aggravated harassment.

The trial continues.
