Veteran opposition leader Chiam See Tong and his wife Lina have retained their leadership positions in the Singapore People's Party (SPP) after a party election on Friday.

Mr Chiam, 78, and Mrs Chiam, 65, who is a Non-Constituency Member of Parliament, remain the secretary-general and chairman of the party respectively.

The election comes about three weeks after the party chose a new 10-member central executive committee (CEC), its top decision-making body.

Among the 10 were four new faces, including an accountant, a former teacher and a non-governmental organisation adviser.

Mr Chiam has been the SPP's secretary-general since the party was established in 1994, leading to some concerns in recent years that the SPP has not been able to renew its leadership.

The SPP said in a press release sent on Saturday: "In an ongoing process of renewal and rejuvenation, the new slate of CEC members is a mix of long-serving young members alongside the party old guard."

It added that this new slate "represents one of the most diverse and representative line-ups in the SPP's history, with CEC members from every age group and from a rich mix of backgrounds".

The party said that it has also been stepping up its presence in Potong Pasir, Bishan-Toa Payoh and Hong Kah North.

This election saw three new young faces put in leadership positions.

They are researcher Loke Hoe Yeong, 29, who is the assistant secretary-general, tutor Arbind Tiwari, 29, the party's assistant treasurer, and human resource consultant Adeline Chan, 27, the organising secretary.
