Morgan was selected as the Liberal Democrat candidate for the
2021 North Shropshire by-election on 16 November 2021. The by-election was triggered after its incumbent MP
Owen Paterson announced on 4 November that he would be stepping down after Prime Minister
Boris Johnson indicated he would no longer prevent his suspension from parliament after being found by a watchdog to have breached rules on lobbying. The government had earlier issued a
three line whip to Conservative MPs to support an amendment to prevent Paterson's sanction and overhaul the watchdog but the following day reversed its position. Paterson had repeatedly lobbied on behalf of healthcare company
Randox and food company Lynn's Country Foods. For the former, he worked as a paid consultant for at least £100,000 per year, and lobbied to secure
government COVID-19 contracts worth nearly £600 million without competitive bidding. At the by-election, Morgan was elected to Parliament as MP for
North Shropshire with 47.2% of the vote and a majority of 5,925. In her victory speech, Morgan attacked Prime Minister
Boris Johnson and the government as being "run on lies and bluster", highlighting the
Westminster Christmas parties controversy and the
Downing Street refurbishment controversy as examples of this, and stated that her priorities would be on improving healthcare locally and supporting the farming community in the constituency. One of her first actions as an MP was writing to
Sajid Javid, the
Secretary of State for Health and Social Care, asking for a review into ambulance waiting times in Shropshire. Local ambulance services had featured as a prominent issue during the by-election campaign. In response to the letter,
Minister of State for Health Edward Argar stated that there had been no impact assessment on the closures of ambulance stations in the area. Morgan was appointed Liberal Democrat Spokesperson for Levelling up, Housing and Communities and Liberal Democrat Spokesperson for Local Government on 11 July 2022. She is a supporter of reopening
Baschurch railway station, which was closed in the 1960s due to the
Beeching cuts. At the
2024 general election, Morgan was re-elected as MP for North Shropshire with an increased vote share of 52.9 per cent and an increased majority of 15,311. ==Personal life==
