The deal will now see Musalia Mudavadi of the United Democratic Forum join forces with Uhuru Kenyatta of The National Alliance and United Republican Party's William Ruto.
The coalition pact was quickly crafted on Tuesday afternoon and was seen by observers as an offensive to the challenge posed by the Raila Odinga, Kalonzo Musyoka, Charity Ngilu and Moses Wetangula Coalition for the Restoration for Democracy.
It's understood that Mudavadi had engaged in lengthy discussions with Peter Kenneth and Gideon Moi throughout Monday night with the aim of forming a coalition but Eugene Wamalwa threw a spanner in the works when he declined to join forces with the Sabatia MP.
The media had been asked to prepare to cover the signing of an agreement between Mudavadi, Kenneth and Moi on Tuesday at 1pm at Nairobi's Freedom Corner, but this was not to be.
The media was then told Kenneth would address a meeting at the Norfolk Hotel at 2.30pm possibly to sign a deal with Mudavadi but this too came a cropper.
Later on Tuesday, the media was alerted that Mudavadi would be heading to Ruto's private office to seal the deal but again turned out to be a wild goose chase.
Towards 6pm, there was indication that a deal had been signed and fresh documents had already been deposited with the Registrar of Political Parties.
Indication was that Mudavadi and Kenyatta will battle it out for the presidential ticket under the TNA-UDF-URP deal but Ruto would remain the running mate whatever the outcome.
