Great Britain voted to leave the European Union in the June 23 (Thursday) referendum but the majority of London voted in favour of remaining.
59.9% of Londoners who went to the polls voted to remain, which went against the rest of the country as Britain voted to leave.
Multicultural areas, a younger population and highly-educated residents are among a number of reasons that have been put forward to explain why London went against the grain.
In west London, the only constituency that voted to leave the EU was Hillingdon , where 56.4% of people who voted to leave, as opposed to 43.6% of people who wanted to remain.
However, Brent voted to remain with a majority of 59.6%, Ealing had a majority of 60.4% in favour of remaining, 70% of people in Hammersmith and Fulham elected to remain, Harrow had 54.6% in favour of remaining.
It was tighter in Hounslow , where 51.1% of people voted to remain as part of the EU as opposed to 48.9% who voted to leave.
One Londoner has even launched a petition for London to become independent from the rest of Great Britain and continue membership.
getwestlondon spoke to MPs and councillors from around west London to find out why they think London and their constituencies voted to remain part of the EU.
London 'a guiding light'
Steve Pound, MP for Ealing North, said: "It was a good result for Ealing but that is just a weak ray of sunshine in a dark and stormy night, which was an appalling night for the rest of the country.
"London, for the most part, voted to remain and was a guiding light and a bit of a beacon.
"I think we're a mature, comfortable and cosmopolitan society and we don't believe in dipping a toe in the stench and the sewage of this undercurrent of racism and xenophobia that other parties have chosen to wade in.
"In London we work with our neighbours, we play with them and we get on with them and we aren't terrified of them and we actually think that we gain from diversity and for many of us, glory in it.
"I don't want to give credit to the MP for Uxbridge for Hillingdon as I'm sure he would take it but I don't know why Hillingdon was so different.
"I think that the Hayes and Harlington end is almost identical to Southall but the Ruislip end has more in similar with South Hertfordshire, but overall the demographic is similar.
"It could be something to do with the airport but I just don't know."
'Cosmopolitan place with educated people'
Rupa Huq, MP for Ealing Central and Acton, said: "Ealing is a cosmopolitan place with an educated population of people from all over the world and I think they understood and recognised the benefits of migration and the contribution that the European Union has made to our lives in every aspect from workers rights to maintaining the peace since 1945, fighting climate change.
"There are many good reasons that our residents in Ealing borough recognised and I'm disappointed that the debate was crowded out by fears about migration elsewhere.
"I'm very proud of the result in Ealing, the people in Ealing voted against divisiveness. We had strong results, particularly in my seat of Ealing Central and Acton in order to remain in the EU.
"I'm disappointed that the clock has been turned back on 40 years of history, but we are where we are."
Cllr Muhammed Butt, Leader of Brent Council, added: "Brent is the most diverse place in the UK and a place where people from all over the world come together to work, live and play.
"This is one of the things I am most proud of about Brent and one of our key strengths.
"My message to our neighbours and co-workers who are EU citizens and also to investors and employers in West London is not to panic. Nothing will change instantly overnight.
"European nationals will continue to enjoy the same rights as they have now and any changes will be publicised well in advance."
