A member of Jeremy Corbyn's front bench has resigned following a row about her son's conviction for possessing drugs at the Bestival event at Lulworth in Dorset.

Shadow international development secretary Kate Osamor was reportedly involved in an altercation with a journalist from The Times after he approached at her north London home for a comment about the case.

According to the paper, the 50-year-old told the reporter she "should have come down here with a bat and smashed your face in".

She was then said to have sworn at him, thrown a bucket of water over him and called the police after accusing him of stalking her.

In a statement posted on her Twitter feed, Ms Osamor said she was standing down to "concentrate on supporting my family through the difficult time we have been experiencing".

The Times said the journalist concerned had been seeking to ask her about previous comments made in relation to the conviction of her son, Ishmael Osamor.

He pleaded guilty at Bournemouth Crown Court to four counts of possession with intent to supply cocaine, MDMA, ketamine and cannabis.

On October 19 he was sentenced to a two-year community order with 200 hours of unpaid work and up to 20 rehabilitation activity days and ordered to pay £400 prosecution costs.

According to The Times, the prosecution in the case accepted Mr Osamor, who had been attending the Bestival music festival in Dorset, was looking after the drugs for friends and was not selling them.

Ms Osamor has faced questions as to why she continues to employ him in her parliamentary office in the House of Commons.
