A senior Labour MP has had the whip suspended after a complaint was made against him.
Conor McGinn's party membership is also understood to have been suspended while allegations are investigated.
The former shadow minister said: “The Labour Party has informed me that it is automatically required to apply a temporary procedural suspension while a complaint is investigated.
“I have not been told the details of the complaint but I am confident that it is entirely unfounded.
“I strongly reject any suggestion of wrongdoing and I look forward to the matter being resolved quickly.”
Mr McGinn, 38, had played a key role in readying the party for the next election, as deputy national campaigns coordinator.
The St Helen's North MP was first elected to Parliament in 2015 and held the seat with a 12,209 majority at the December 2019 election.
He also supported the successful campaign for Helen's law, which makes it clear that murderers and evil sexual offenders who refuse to reveal the location of the remains of their victims cannot be granted parole.
The law was named after Helen McCourt, who vanished on her way home from work in 1988, aged 22.
It also applies to paedophiles who refuse to identify those they abused.
Helen's killer Ian Simms died this year without telling where he hid her body.
The victim's mum Marie said he "got what he deserved", but she vowed to carry on searching for her daughter.
Helen's mum said she is glad killer Ian Simms has been "wiped off the earth" after he died - taking the secrets of where her daughter is buried to his grave.
Depraved Simms, 64, strangled Helen as she walked home from work but never revealed where her body is.
