However Liam Fox, the International Trade Secretary, said that it was "not in any way forbidden" to speak to the Prime Minister of another country without telling the Foreign Secretary first. Patel's "startling admissions" raise doubts about whether she can continue in her role - with Labour also demanding that she resign, the Daily Mail says.
Tory ministers said that Ms Patel should be "toast" after the International Development Secretary issued an apology for failing to disclose that she held 12 meetings in 12 days in August without informing the Foreign Office.
During a meeting with Israeli Prime Minister Benjamin Netanyahu, she discussed her family background that included her parents fleeing Uganda in the 1970s and settling in Britain.
Kate Osamor, her Labour shadow, branded Ms Patel's absence "simply unacceptable", a criticism echoed by the SNP's spokesman, Stephen Gethins. The secretary of state would like to take this opportunity to clarify that this was not the case.
In her clarification, Patel was forced to admit that she did not just meet with "people and organisations".
Patel insisted that she had gone to Israel on a "family holiday" but her trip, which was organised by Lord Polak honorary president of Conservative Friends of Israel, was described by critics as an attempt to win favour with wealthy pro-Israeli Conservative donors who could fund a potential future leadership campaign. The Foreign Office, it said, was "clear that United Kingdom interests were not damaged or affected by the meetings on this visit". I am sorry for this and I apologise for it.

"The Prime Minister has asked the Cabinet Office to look at how the code can be made clearer and tightened", a Downing Street spokesperson said.
On Monday, Ms Patel issued a statement to say her Tel Aviv meetings were to discuss "prospects for closer collaboration between Israel and the United Kingdom on development and humanitarian issues".
Andy Slaughter, a member of parliament for the main opposition Labour Party and a vice-chair of the Labour Friends of Palestine and the Middle East, told Middle East Eye on Friday that Patel's actions had been "outrageous" and compromised Britain's standing as an "honest broker" in distributing aid around the world.
On Tuesday No.10 confirmed Patel had suggested the United Kingdom send aid money to the Israeli army in the Golan Heights. United Kingdom ministers are required to notify the Foreign Office when conducting official business overseas, but Patel admitted that she failed to do so.
"The prime minister met the secretary of state this morning to remind her of the obligations which exist under the ministerial code".
The Secretary of State said she had seen for herself the work of Jewish charities in Israel, and said she was "struck by the achievements of the state of Israel".
