So why are parents in Southall and Slough (my hometown) doing such things. In those towns it's more like 'spot the white person'.
As for names like Sukhdeep, the Sikhs born here would know the innuendo associated with that name and avoid it. They can go for a simple easy to pronounce name like Preeti. No need for 'Jessica'.
But some people are hell bent on giving their kids a western name and will look for any excuse to so.
