Hi,
I am speaking from my own experience having moved from Canada to the UK on a spouse visa in 2000.
The first thing to understand is that if you are not from the EU , you will need some type of visa to be able to live here and work here for this you can have a look at the visa (government) website:

You need to have your visa before coming ito the UK, you have to apply from your country.
If you find a visa that allows you to come here, you will have to search what type of work you are looking for.
If you have a degree but no experience, I would suggest that you get some work experience in your country before trying here, I find that in the UK work experience is more important than degrees.
If it is easy to find a job? Well it depends..it's probably very easy to find a low paid job but it is something else to find a professional job. Your first job in the UK will be hard to find because employers prefer if you have experience in the country.
To give you an example, I came here and I already had a degree in IT (Canada) and I worked for about 4 years for a bank in Canada as a software developer (Lotus notes/Domino) so I had a lot of experience in my specialised field. I do not agree with some of the posts here that say it is easier for an immigrant to find a job because of the anti-discrimination laws, it certainly was not in my case. It was not easy to find my first Lotus notes developer job in the UK , employers are simply not really interested in getting the references from another country (I can understand that).
I really cannot see from my experience that employers will employ ethnic minorities regardless of their skills, but I can't say that it does not happen, however if that does happen, I would say that it is in a minority of cases.
