A train driver has been suspended for putting up a poster of Queen Elizabeth at work.
The London Underground worker has been suspended and forced to remove the A4 sized image of the monarch while bosses investigate a complaint.
However, Union chiefs have now demanded that he return to work and put the poster – which is said to have caused an argument between the man and his colleague – back up.
The men – who both work on the Central line and are said to be members of rival unions who have "vastly different political allegiances" – have clashed over the poster numerous times.
Central line operations director Peter McNaught told the Daily Star newspaper: "Following a dispute between two members of staff on the Central line, a full investigation is being carried out by senior managers and a member of staff has been suspended pending the outcome.
"We take all claims of bullying and harassment extremely seriously and do not tolerate such behaviour in the workplace."
The reprimanded driver has been accused of bullying his colleague but union boss Finn Brennan says he denies all allegations.
He said: "It is extraordinary a public corporation under the control of London Mayor Boris Johnson is instructing staff to remove photographs of the Queen.
"We have written to the company to ask them for an immediate investigation and for this bizarre decision to be reversed."
