Nearly 3,000 so-called honour attacks were recorded by police in Britain last year, new research has revealed.
According to figures obtained by the Iranian and Kurdish Women's Rights Organisation (Ikwro), at least 2,823 incidents of 'honour-based' violence took place, with the highest number recorded in London.
The charity said the statistics fail to provide the full picture of the levels of 'honour' violence in the UK , but are the best national estimate so far.
The data, taken from from 39 out of 52 UK forces, was released following a freedom of information request by Ikwro.
In total, eight police forces recorded more than 100 so called honour-related attacks in 2010.
The Metropolitan Police saw 495 incidents, with 378 reported in the West Midlands, 350 in West Yorkshire, 227 in Lancashire and 189 in Greater Manchester.
Cleveland recorded 153, while Suffolk and Bedfordshire saw 118 and 117 respectively, according to the figures.
Between the 12 forces able to provide figures from 2009, there was an overall 47 per cent rise in honour attack incidents.
Police in Northumbria saw a 305 per cent increase from 17 incidents in 2009 to 69 in 2010, while Cambridgeshire saw a 154 per cent jump from 11 to 28.
A quarter of police forces in the UK were unable or unwilling to provide data, Ikwro said.
The report stated: 'This is the first time that a national estimate has been provided in relation to reporting of honour-based violence.
'The number of incidents is significant, particularly when we consider the high levels of abuse that victims suffer before they seek help.'
'Honour' attacks are punishments usually carried out against Muslim women who have been accused of bringing shame on their family and in the past have included abductions, mutilations, beatings and murder.
Ikwro director Diana Nammi told the BBC that families often deny the existence of the attacks.
She said: 'The perpetrators will be even considered as a hero within the community because he is the one defending the family and community's honour and reputation.'
Calling for more support for victims, she added: 'For some cases, police and some organisations just help them up to a length of time, then they will stop. With honour-based violence, the threat may be a lifetime threat for them.
1400 years is a lifetime.
