Firstly I would say "no" but there is no such thing as "a British accent".There are many different variations. People in Scotland,Ireland,Wales and the North of England speak differently from those in the South and around London.Even within London there is a difference between different areas,and different backgrounds of people.If you watch the movie "Pygmalion" or "My Fair Lady" they explain the differences that existed between high and low class people,but even today that exists. So I would not pronounce them the same,but maybe someone else might find them similar.
