Mr Johnson, who is now on holiday in the Caribbean, is also expected to issue a New Year message to the country in the coming days.
In the message, Mr Corbyn said: "2019 has been quite the year for our country and for our Labour movement".
Politicians from the party and commentators piled on to the leader's comments in his New Year message.
Former and current Labour MPs blamed Corbyn for the party's crushing defeat during the 12 December election, which saw Labour lose 59 seats in Parliament.
In making his announcement, he shared an article in which he set out his thoughts on why Labour lost so and how the party rebuilds, promising to outline more in the new year. And the period ahead could not be more important.
She stated: "I hope in November, our long global nightmare will be over and Donald Trump will be dumped out of office by the American people, and we will finally see the United States resume its role as a global leader on the issues that matter to us all".
"It won't be easy". But we have built up a movement.
Boris Johnson has ordered a major probe into the leaking of confidential Government documents to Labour during the election campaign.
The letter highlighted the party's loss of seats "in every region...with the biggest swing against us from the poorest people".
In his speech, Corbyn spoke out against billionaires and said Labor would "be at the forefront, both in parliament and on the street".
Labour's Richard Burgon has announced that he will be putting himself forward to become the party's next deputy leader.
"I thought, as soon as the leader loses the confidence of the parliamentary party it's nearly impossible to see how you can form a government", Watson said.
Neil Coyle, the Labour MP for Bermondsey and Old Southwark, slammed his leader and encouraged people to join the party.
In the wake of the election, former Labour prime minister Tony Blair placed the blame for the loss firmly at Corbyn's feet, saying he had pursued a policy of "almost comic indecision" on Brexit that alienated voters on both sides of the debate.
