The decision comes immediately after the High Court allowed Dr Ekuru Aukot to be on the ballot.
In a letter to the Coalition, IEBC chairman Mr Wafula Chebukati confirmed receipt of the letter of the Mr Odinga and his running mate Mr Kalonzo Musyoka of the intention to quit the race, but failed to fill a special form 24A which would have legally made them withdraw.
“We note that the Rt Honorable Raila Amolo Odinga and his running mate sent a letter dated October 10 2017 indicating that they had decided to withdraw from the Fresh Presidential elections,” IEBC said in a statement.
“They however have not submitted the statutory Form 24A,” IEBC said adding that the commission, upon receipt of the form, will process the request as required by the law.
Form 24A, according to the IEBC, is a special form through which a presidential candidate notifies the commission of the intention to quit the race.
Mr Odinga and his running mate Mr Kalonzo Musyoka, however, never submitted the said form. Mr Odinga will therefore be on the ballot on the October 26 polls.
The new discovery by the polls team, gives it a leeway to have the ballot papers bearing the name of the former Prime Minister in the repeat polls, in which he will now be facing off with the incumbent Mr Uhuru Kenyatta and Thirdway Alliance presidential candidate Dr Ekuru Aukot.
In Wednesday in the ruling by High Court judge Mr John Mativo, ruled that all the eight presidential candidates who faced off the bungled August 8 presidential elections have the right to be on the ballot in the repeat polls slated for October 26.
Meanwhile, Mr Odinga left the country on Wednesday evening for UK and it is understood that he will be going through the US in a series of talks.
Earlier, Mr Chebukati had in a gazetted notice dated September 5, said that Jubilee’s Uhuru Kenyatta and his running mate Mr William Ruto and ODM’s Raila Odinga and his running mate Kalonzo Musyoka would be the only candidates on the ballot.
The Commission had argued that the decision was informed by the 2013 presidential decision, a move High Court Judge Mr John Mativo quashed on Wednesday.
