Secretary-general of the Progress Singapore Party (PSP), Tan Cheng Bock, met Prime Minister Lee Hsien Loong's brother, Lee Hsien Yang, for a breakfast meeting on June 24 morning.

Due to the rain and it being rather early, the market was visibly less crowded even though the entourage garnered some attention.

Joining them were three other members from the Central Executive Committee, including assistant secretary-general Leong Mun Wai as well as members Yuen Kin Pheng, Francis, and Michael Chua.

All five of them were spotted in the PSP red and white polo-shirt.

The Straits Times reported that Lee has joined the party as a member "for quite some time" and Tan gave Lee the party's membership card this morning.

While speaking to the press, Tan said that Lee had joined the party about "three months ago".

When the media asked if he is contesting in the upcoming election, Lee said, "You'll find out".

It is also unclear if Lee is supporting the party financially but he told media "that's possible".
