By 1966, it had become clear the British government could no longer afford to administer and protect what is now the United Arab Emirates. British Members of Parliament (MPs) debated the preparedness of the Royal Navy to defend the sheikhdoms. Secretary of State for Defence Denis Healey reported that the British Armed Forces were seriously overstretched and in some respects dangerously under-equipped to defend the sheikhdoms. On 24 January 1968, British Prime Minister Harold Wilson announced the government's decision, reaffirmed in March 1971 by Prime Minister Edward Heath, to end the treaty relationships with the seven Trucial Sheikhdoms, that had been, together with Bahrain and Qatar, under British protection. Days after the announcement, the ruler of Abu Dhabi, Sheikh Zayed bin Sultan Al Nahyan, fearing vulnerability, tried to persuade the British to honour the protection treaties by offering to pay the full costs of keeping the British Armed Forces in the Emirates. The British Labour government rejected the offer. After Labour MP Goronwy Roberts informed Sheikh Zayed of the news of British withdrawal, the nine Persian Gulf sheikhdoms attempted to form a union of Arab emirates, but by mid-1971 they were still unable to agree on terms of union even though the British treaty relationship was to expire in December of that year.
