Answer:
It is Reform Judaism as Eddie J noted.
Reform Judaism in the UK and the US differ somewhat so I will address Reform Judaism in the United States, the branch of Judaism that I belong to, and in which I was raised.
As Aryeh indicates, Refom Judaism has returned to a much more traditional form of worship. I am 50 years old. Even growing up as a Reform Jew, I never even knew Reform ever had Sunday worship until I began to read the history of the movement after I was an adult. When I was a child, the Sabbath Services were about half English, half Hebrew..today, more than 3/4 of the service is in Hebrew. (our prayerbooks still have everything in Hebrew translated there and now transliteration is also often provided)
A significant number of our congregants were raised Orthodox or Conservative or had Orthodox parents. My own father was raised Orthodox, but my mother was raised Reform. The Reform Judaism of my Grandmotherwho came to the Reform synagogue in 1914 from an Orthodox background,and my mother, born in 1927, was already FAR removed from Sunday worship and many other things Aryeh mentions above. I have the prayerbooks they used and even the books used from the Religious school at that time. My Grandmother's Reform involvement was very strong in the Zionist movement decades before WW2. I believe the best way to know what Reform Jews believe is to read the Statement of Principles for Reform Judaism by the
Central Conference of American Rabbis
