Boris Johnson would secure a 104-seat majority under proposed boundary changes that could be introduced before the next election, an exclusive analysis reveals.

The Conservatives would have twice as many seats as Labour under the reforms which were put forward by the Boundary Commissions in 2018 for a slimmed down 600-seat House of Commons.

The Tories would have 352 seats (just 13 down from their 365 seats in the new Parliament) compared to Labour’s 174 (down 29 seats on their current showing), with the SNP in third place on 47 (just two down).

The Liberal Democrats would drop another four seats to have just seven MPs, tied with Sinn Fein and the Democratic Unionist Party (DUP).

High-profile figures from both sides of the Commons would be at risk of seeing their seats disappear in such a boundary shake-up including Stephen Kinnock, Simon Hart, the new Welsh Secretary, Priti Patel, the Home Secretary, Ian Blackford, the SNP leader, and Ian Lavery, the Labour party chairman.
