The Parliamentary hopeful for the Calder Valley attacked her boyfriend's car when their affair ended, it was learned this week

She scratched Craig Moore's BMW close to The Fox and Goose in Hebden Bridge.

The mother-of-three was cautioned but not charged.

She said: "The end of this relationship was a very difficult part of my life.

“I genuinely regret it, but everyone makes mistakes."

Ms Oosthuysen, of Unity Street, Hebden Bridge, was chosen ahead of Cherie Blair's stepmother, Steph Booth, by Labour last month.

She now faces an anxious wait to see if she will be confirmed by Labour’s national executive committee as the prospective Parliamentary candidate for the Calder Valley.

Chairwoman of the Calder Valley Labour Party, Judy Gannon, said: “It’s a very personal thing and I hope it won’t affect her too much, politically.”

A spokesman for the Yorkshire and the Humber Labour Party said Ms Oosthuysen was expected to appear before the committee in the next month or so.

“I would not want anyone to think that Labour does not take police matters seriously but it is not something we are taking up seriously as an issue.”

He refused to comment on whether the NEC might take a dim view of Ms Oosthuysen’s actions.
