San Francisco: Facebook believes the data of up to 87 million people was improperly shared with the political consultancy Cambridge Analytica -- many more than previously disclosed.

The BBC has been told that about 1.1 million of them are UK-based.

The overall figure had been previously quoted as being 50 million by the whistleblower Christopher Wylie, BBC reported on Wednesday.

Facebook chief Mark Zuckerberg said "clearly we should have done more, and we will be going forward".

During a press conference he said that he had previously assumed that if Facebook gave people tools, it was largely their responsibility to decide how to use them.

But he added that it was "wrong in retrospect" to have had such a limited view.

"Today, given what we know... I think we understand that we need to take a broader view of our responsibility, that we're not just building tools, but that we need to take full responsibility for the outcomes of how people use those tools as well," he said.

Zuckerberg also announced an internal audit had uncovered a fresh problem. Malicious actors had been abusing a feature that let users search for one another by typing in email addresses or phone numbers into Facebook's search box.

As a result, many people's public profile information had been "scraped" and matched to the contact details, which had been obtained from elsewhere.

"It is reasonable to expect that if you had that (default) setting turned on, that in the last several years someone has probably accessed your public information in this way," Zuckerberg said.

The estimates of how many people's data had been exposed were revealed in a blog by the tech firm's chief technology officer, Mike Schroepfer.

BBC has also learned that Facebook now estimates that about 305,000 people had installed the This Is Your Digital Life quiz that had made the data-harvesting possible. The previously suggested figure had been 270,000.

About 97 per cent of the installations occurred within the US. However, just over 16 million of the total number of users affected are thought to be from other countries.

Facebook has faced intense criticism after it emerged that it had known for years that Cambridge Analytica had collected data from millions of its users, but had relied on the London-based firm to self-certify that it had deleted the information.

Cambridge Analytica said it had bought the information from the creator of the This Is Your Digital Life app without knowing that it had been obtained improperly.

During Zuckerberg's press conference, Cambridge Analytica tweeted it had only obtained data for 30 million individuals -- not 87 million -- from the app's creator, and again insisted it had deleted all records.

Thiruvananthapuram (PTI): Buoyed by the strong performance of the Congress-led UDF in the local body polls, KPCC president Sunny Joseph said on Saturday that the front's results indicated the people had rejected the LDF government.

According to early trends, the UDF was leading in more grama panchayats, block panchayats, municipalities and corporations than the LDF.

The local body polls were held in two phases in the state earlier this week.

Speaking to reporters here, Joseph said the people of Kerala had extended their support to the UDF.

"We could expose the LDF government’s anti-people stance and the people understood it. The LDF’s fake propaganda was rejected by the people. The UDF is moving towards a historic victory," he said.

He said a united effort, proper preparations, good candidate selection and hard work had resulted in the Congress and the UDF’s victory in the elections.

Asked about the prospects in the Thiruvananthapuram Corporation, Joseph said the party was studying the matter and would comment later.

LDF convenor T P Ramakrishnan said the results would be closely examined.

According to him, the government had done everything possible for the people.

"Why such a verdict happened will be examined at the micro level. People’s opinion will be considered and further steps will be taken," he said.

He added that decisions would be taken after analysing the results. "If any corrective measures are required, we will initiate them and move forward," he said.

AICC leader K C Venugopal said the results showed that people had begun ousting those who, he alleged, were responsible for the loss of gold at Lord Ayyappa’s temple.

"This trend will continue in the Assembly elections as well. It is an indication that the people are ready to bring down the LDF government," he said.

Venugopal said the UDF had registered victories even in CPI(M) and LDF strongholds.

"I congratulate all UDF workers for their hard work. Congress workers and leaders worked unitedly," he said.

Referring to remarks made by Chief Minister Pinarayi Vijayan against the Congress on polling day, Venugopal said the voters had responded through the verdict.

"I do not know whether the chief minister understands that the people are against him. Otherwise, he does not know the sentiment of the people. The state government cannot move an inch further," he said.

He said the results indicated a strong comeback for the UDF in Kerala.

Asked whether the Sabarimala gold loss issue had affected the LDF in the local polls, Venugopal said the CM and the CPI(M) state secretary did not take the issue seriously.

"We took a strong stand on the matter. The BJP played a foul game in it," he alleged.

On the BJP's role in the local body elections, Venugopal alleged that the party operated with the CPI(M) 's tacit support.

"The CPI(M) supported the central government on issues such as PM-SHRI, labour codes and corruption in national highway construction. The CPI(M) is facing ideological decline, and the state government’s policies are against the party’s own decisions," he said.

Meanwhile, LDF ally Kerala Congress (M) leader Jose K Mani said the party could not win all the wards it had expected in the elections.

He congratulated winners from all parties and said the party would closely examine the losses and identify shortcomings. "Later, we will take corrective measures," he added.

Senior Congress leader and MP Rajmohan Unnithan said the trends in the local body elections indicated that the UDF would return to power in the 2026 Assembly elections.

"We will win 111 seats as in 1977 and return to power in 2026. The anti-government sentiment of the people is reflected in the elections," he said.

Unnithan said the people were disturbed and unhappy with the present government.

"The trend indicates the end of the LDF government," he added.

CPI(M) MLA M M Mani said the people had shown ingratitude towards the LDF despite benefiting from welfare schemes.

"After receiving all welfare schemes and living comfortably, people voted against us due to some temporary sentiments. Is that not ingratitude," he asked.

Mani said no such welfare initiatives had taken place in Kerala earlier.

"People are receiving pensions and have enough to eat. Even after getting all this, they voted against us. This is what can be called ingratitude," he said.

Muslim League state president Panakkad Sayyid Sadiq Ali Shihab Thangal said the results were beyond expectations.

"The outcome points towards the Secretariat in Thiruvananthapuram, indicating that a change of government is imminent. We are going to win the Assembly election," he said.
