Prime Minister Lawrence Gonzi had a meeting with Franco Debono this evening, two days after the Nationalist MP missed two votes in parliament, denying the government its majority.
Dr Debono also did not attend a meeting of the PN parliamentary group on Tuesday, and could not be contacted.
Party whip David Agius late on Tuesday denied claims that pressure was being put on Dr Debono to resign.
Dr Debono attended the first part of Monday's parliamentary sitting, but was absent during two votes on amendments to a motion on the setting up of a Select Committee. The Speaker had to use his casting vote.
Dr Debono later returned to the Chamber and voted with the government. The motion was approved.
This evening's meeting was held at Dr Debono's residence in Ghaxaq. Mrs Gonzi also attended.
