From 1920-48 did the British deliberately try to create an Arab majority in israel AKA Western Palestine?

For politically motivated reasons, the British government deliberately tried to create an artificial Arab majority in Israel by severely restricting Jewish immigration and actively encouraging illegal Arab immigration. Reference to Arab immigration into Palestine during the 1920s is made as well in the British mandatory government's annual compilation of statistical data on population. The Palestine Blue Book, 1937, for example, provides time series demographic statistics whose annual estimates are based on extrapolations from its 1922 census.[24] The footnote accompanying the table on population of Palestine reads: There has been unrecorded illegal immigration of both Jews and Arabs in the period since the census of 1931, but it is clear that, since it cannot be recorded, no estimate of its volume is possible.[25] The 1935 British report to the League of Nations noted that: One thousand five hundred and fifty-seven persons (including 565 Jews) who, having made their way into the country surreptitiously, were later detected, were sentenced to imprisonment for their offence and recommended for deportation.[26] The number who "made their way into the country surreptitiously" and undetected was neither estimated nor mentioned.

To my knowledge, the British conquered that region in order to establish a colonial territory. After W.W.2, they then handed control of that colonial settlement over to the newly created U.N. The U.N. decided how the land should be controlled by the Jews and Arabs. - Pepper.
