Britain will send a Royal Fleet Auxiliary ship laden with aid supplies to Haiti, International Development Secretary Douglas Alexander has told MPs.
He made the announcement at his departmental question session in the Commons on 20 January 2010, shortly after the devastated country was hit by a strong aftershock.
Mr Alexander told MPs the British search and rescue team was safe following the quake.
He offered the government's sympathy to the victims of the Haiti earthquake and spoke of the "great collective pride" in the actions of the UK search teams in Port-au-Prince.
Shadow international development secretary Andrew Mitchell added: "I am sure the whole House will be united today in sorrow for the people of Haiti in this moment of crisis.
"We also pay tribute to the energy and determination of the aid workers and NGOs who are working tirelessly and to the incredible generosity of the British people."
Liberal Democrat international development spokesman Michael Moore said: "May I join in the tributes to the British contribution made on the ground and the generosity of people in giving their donations."
