They were clear about LKY being a British stooge. They were suspicious of him before the elections in 1959. The British did everything for LKY to remain afloat. All that LKY had to do was to rely on his British masters, even when it came to wresting back the leadership of the PAP well before the 59 elections.
Even when Singapore was part of Malaysia, the British "rescued" their "favored son" from being arrested under the ISA!
The British helped LKY, the only Englishman east of Suez, all the way for his obedient service to the British Crown.
