PAP leaders believed that Singapore's future lay with Malaya, due to strong ties between the two. It was thought that reuniting with Malaya would benefit the economy by creating a common market, alleviating ongoing unemployment woes in Singapore. However, a sizeable pro-communist wing of the PAP was strongly opposed to the merger, fearing a loss of influence, and hence formed the Barisan Sosialis, splitting from the PAP. The ruling party of Malaya, United Malays National Organisation (UMNO), was staunchly anti-communist, and it was suspected UMNO would support the non-communist factions of PAP. UMNO, initially sceptical of the idea of a merger due to distrust of the PAP government and concern that the large ethnic Chinese population in Singapore would alter the racial balance in Malaya on which their political power base depended, became supportive of the idea of the merger due to joint fear of a communist takeover.
