The desecration of Australian army graves in Harefield, which were found covered in blue paint on Sunday 22 November, has left onlookers 'sickened'.
The perpetrators must wake up to their 'atrocious' actions and should be made to volunteer with armed forces charities, according to Cliff Dixon, chairman of UKIP Hillingdon.
It is the second time this year that such vandalism has occurred in Harefield. In April, vandals targeted a memorial to commemorate 100 years since Australian and New Zealand army forces landed in Gallipoli, Turkey, during World War One.
Mr Dixon said: “This kind of thing is such an insult, it’s disgraceful. When you think that there are people laying there who gave their lives for our freedom and some mindless moron is prepared to go and desecrate their memorial.
“They should first be made to go back and make sure that those graves are cleaned up and are absolutely immaculate. They should make sure they not only tidy those graves, but are then responsible for keeping them that way all year.
“I would get them to put on a very large amount of community service working for forces charities so they get to appreciate who they’ve insulted and appreciate what those people have died for.
“Maybe it’ll wake them up to realise what they’ve done is atrocious and appreciate whose memories they’ve insulted.”
He added: “This kind of crime does need to be given a much higher priority.”
He also believes the education system has failed to place enough emphasis around British history and the sacrifices of the armed forces.
Chris Summers, who fought Boris Johnson to be the Uxbridge and South Ruislip MP as Labour candidate at the May election, said: "I am horrified to hear that the graves of Australian soldiers have been desecrated at Harefield. These people gave their lives fighting alongside the British during the two world wars.”
Mr Summers, who is an Ealing Councillor, said: "At a time when we face this mortal threat from ISIS/Daesh we should be more grateful than ever to the police and armed forces who keep us safe.”
Inspector Rob Bryan said: “At this time we have made one arrest and that person remains on police bail. All lines of enquiry remain open for this specific case and it is really too early to establish motive.
“Whatever their reasoning, it is a crime that has sickened people around the world. We appreciate the impact such a crime has on the village and indeed the wider global community. We continue to work hard in reviewing all available CCTV and progressing forensic leads.”
