During his childhood and youth, Grey had spent time with his unmarried uncle, Sir Henry Grey, at
Howick Hall. In 1801, Grey and his family would take up residence at Howick Hall, and he inherited the estate when his uncle died in 1808. His maiden speech in the
House of Commons in February 1787 was an attack on Pitt's
Commercial Treaty with France. The speech was greeted with applause;
Henry Addington wrote: "I do not go too far in declaring that in the advantage of figure, voice, elocution, and manner, he is not surpassed by any member of the House" and lamented the fact that the speech had firmly placed Grey in the ranks of the opposition. In April 1792, Grey was one of the founders of the
Society of the Friends of the People, a group of 147 people including 28 MPs and three peers that campaigned for parliamentary reform. As a member of the committee who ran the society, Grey was careful to advocate moderation in calls for reform in order to distance themselves from the actions of French revolutionaries and to protect themselves from accusations of insurrection. The society’s manifesto said that its aim was to "reinstate the constitution upon its true principles" and indicated that Grey would move for reform in the next parliamentary session. On 6 May 1793, Grey duly moved that a petition of the society, which outlined the abuses of the electoral system and called for parliament "to regulate the right of voting upon a uniform and equitable principle", should be put before a parliamentary committee. Following a debate, the motion was defeated by 282 votes to 41, in spite of a supporting speech by Fox. Grey, together with Fox and their supporters, also mounted challenges to the government's repressive measures against radicals, which culminated in the
1794 Treason Trials, and called for peace with France. In the 1796
general election Grey was returned unopposed. In May 1797, a second motion for electoral reform was lost by 256 votes to 91. During the debate, both Grey and Fox indicated that, if the motion was not carried, they and their supporters would secede from parliament and only attend to vote on important measures. The secession, which Grey came to regret, lasted about three years, leaving Grey free to return to Howick, where he and his wife lived as guests of his uncle. In the 1799 session, he returned to parliament for the debates concerning Ireland, his marriage to
Mary Ponsonby, who was from an Irish liberal family, having given his a particular interest in Irish affairs. By November 1800 he was participating more fully in debates in parliament, and was joined by Fox in March 1801. In 1801, Grey's father accepted a peerage from the new prime minister
Henry Addington and became Baron Grey, much to the dismay of Grey, as he had hoped to have a long career in the House of Commons rather than having to move to the
House of Lords on inheriting the peerage. That same year, Grey's uncle offered Howick as a permanent residence to Grey and his growing family. Grey became increasingly attached to Howick and notoriously reluctant to make the journey to London to attend to political affairs. When Pitt returned to power in 1804, he made approaches to
Lord Grenville, who was by this time aligned with the Whigs, and Grey, who was now in support of the war against
Napoleon following the breakdown of the
peace of Amiens, to join a coalition government. Both refused to join the cabinet without Fox, and
King George III was adamant that Fox could not be included, so the approaches came to nothing. ==Ministry of All the Talents, 1806–1807==
