All parliamentary groups, aside from the far-right Alternative for Germany (AfD) party, warned that Israel's plans to annex parts of the West Bank would jeopardize Israel's security and hopes of a two-state solution. "An annexation decision could not be left without consequences and we are examining different options at a national level and also in coordination with our main European partners".
'It is with sadness that I have followed the proposals to annex Palestinian territory, ' he wrote.
Although Netanyahu has insisted he is continuing to work with U.S. interlocutors from the Trump administration over the timing for annexation, he has appeared increasingly isolated within his own cabinet and internationally over the proposals. They contend that it would make an independent Palestinian state nonviable.
Mr Johnson went on to say that if Israel does push ahead with annexation then Britain would not recognise the changes to Israel's borders, unless they were also agreed on by the Palestinians.
Netanyahu himself said Tuesday that his discussions with US officials would continue in the "coming days", suggesting a delay in plans to declare sovereignty over a significant chunk of the Jewish settlements in the region.
For weeks, observers of Israel and the Palestinian territories have had July 1 circled on the calendar. He said he expected the annexation to take place later in July.

Israel's foreign minister claimed a move toward the proposed annexation of occupied West Bank land was unlikely on Wednesday, the start date set by Prime Minister Benjamin Netanyahu's government for discussing such a move.
The prime minister's office issued a statement saying that Netanyahu held discussions Wednesday with American diplomats and Israeli defense officials on the issue of annexation, and that "additional discussions will be held in the coming days".
Palestinian President Mahmoud Abbas said the plan "belongs to the dustbin of history". US officials have said they don't want to move forward without both leaders in agreement.
Johnson insisted that the United Kingdom had often been in a small minority of countries at the UN in "defending Israel against unwarranted and wholly disproportionate criticism", claiming annexation would be a "gift" to those that sought to "perpetuate old stories" about the Israeli state.
The step would be in line with a blueprint announced by Donald Trump in January under which Israel would control of 30 per cent of the West Bank.
There has even been domestic opposition in Israel with the country's defence minister and alternate Prime Minister, Benny Gantz, who has said annexation must wait until the coronavirus crisis has been contained.
