Seats visited by the main party leaders so far during the election campaign

The main party leaders have visited a wide range of constituencies across the UK since the campaign began, but though the locations have been different, many of the seats share one thing in common.

Rishi Sunak, Sir Keir Starmer and Sir Ed Davey have focused almost exclusively on constituencies the Conservatives are defending at the election, with few visits elsewhere.

Some of the constituencies they have visited have huge Tory majorities.

Mr Sunak has campaigned in eight constituencies where the Tories are defending notional majorities of more than 20,000, including his own seat of Richmond & Northallerton.

Meanwhile, Labour leader Sir Keir and his Liberal Democrat counterpart Sir Ed have visited seats where the Conservatives are defending notional majorities as high as 16,758 (Reading West & Mid Berkshire), 18,731 (Basingstoke), 19,020 (Stratford-on-Avon) and 20,543 (Shropshire North).

Here are details of all the seats visited by the three leaders so far, from the first day of the campaign on Thursday May 23 up to and including Friday June 21, based on analysis by the PA news agency.

– Rishi Sunak

The Prime Minister has visited 40 constituencies since the start of the campaign, with the vast majority – 36 – being seats his own party is defending.

He has held an event in just two seats that are being defended by Labour (Blyth & Ashington and Cambridge), along with one seat defended by the SNP (Caithness, Sutherland & Easter Ross) and one by the DUP (Belfast East).

Of the 36 Conservative-held seats Mr Sunak has visited, 21 are being targeted by Labour and 15 by the Liberal Democrats.

The Labour targets visited by the Prime Minister are, in order of vulnerability (size of swing needed to change hands): Bury North (number seven on Labour’s target list), Stroud (number 14), Vale of Glamorgan (22), Clwyd North (29), Milton Keynes Central (46), Clwyd East (48), Redcar (51), Cities of London & Westminster (56), Bishop Auckland (90), Crawley (92), Harrow East (94), Stoke-on-Trent North (103), Macclesfield (109), Erewash (120), Great Grimsby & Cleethorpes (134), Swindon North (161), Northamptonshire South (295), Cannock Chase (304), Thirsk & Malton (319), Grantham & Bourne (334) and Richmond & Northallerton (343).

The Lib Dem targets visited by Mr Sunak are Wimbledon (number three on the Lib Dems’ target list), St Ives (number 16), Didcot & Wantage (27), Wokingham (35), Devon North (47), Harpenden & Berkhamsted (51), Melksham & Devizes (66), Horsham (68), Chesham & Amersham (76), Devon Central (121), Suffolk Coastal (133), Torridge & Tavistock (144), Cornwall South East (153), Hinckley & Bosworth (194) and Honiton & Sidmouth (266).

The Lib Dems would take Wimbledon on a swing of 0.8 percentage points and Labour would take Bury North on a swing of 1.2 points.

By contrast, Honiton & Sidmouth would fall to the Lib Dems on a swing of 25.5 points, while Richmond & Northallerton – Mr Sunak’s own seat – would fall to Labour on a swing of 23.5 points.

– Sir Keir Starmer

The Labour leader has visited 36 constituencies since the start of the campaign, 26 of which are being defended by the Conservatives, three by the SNP, one by the Greens and six by Labour.

The 26 Tory seats that Sir Keir has visited are Bury North (number seven on Labour’s target list), Bolton North East (number eight), Vale of Glamorgan (22), Chipping Barnet (37), Southampton Itchen (47), Redcar (51), Swindon South (55), Crewe & Nantwich (60), Worcester (70), Worthing East & Shoreham (76), Filton & Bradley Stoke (82), Uxbridge & South Ruislip (84), South Ribble (95), Stevenage (98), Finchley & Golders Green (105), York Outer (106), Monmouthshire (111), Great Grimsby & Cleethorpes (134), Basingstoke (137), Bassetlaw (151), Stafford (153), Thurrock (156), Halesowen (159), Nuneaton (171), Gillingham & Rainham (201) and Reading West & Mid Berkshire (209).

The swings needed by Labour to win these seats from the Tories range from 1.2 percentage points in Bury North to 17.0 points in Reading West & Mid Berkshire.

The three SNP seats visited by Sir Keir are Glasgow East (number 83 on the target list), Inverclyde & Renfrewshire West (102) and Bathgate & Linlithgow (138), while the Green seat is Brighton Pavilion (213).

The six Labour defences Sir Keir has visited are Bristol North West, Derby South, Holborn & St Pancras – the seat in which he is standing – Manchester Central, Queen’s Park & Maida Vale and Portsmouth South.

– Sir Ed Davey

The Liberal Democrat leader has visited 33 seats, 29 of which are being defended by the Conservatives, two by Labour, one by the SNP and one by the Lib Dems.

The 29 Tory seats that Sir Ed has visited are Carshalton & Wallington (number one on the Lib Dems’ target list), Wimbledon (number three), Cambridgeshire South (number five), Cheltenham (six), Cheadle (eight), Eastbourne (nine), Westmorland & Lonsdale (15), Winchester (19), Harrogate & Knaresborough (21), Woking (24), Brecon, Radnor & Cwm Tawe (25), Eastleigh (26), Dorking & Horley (29), Newbury (34), Wokingham (35), Devon South (40), Frome & East Somerset (number 43), Chippenham (45), Glastonbury & Somerton (48), Tunbridge Wells (49), Harpenden & Berkhamsted (51), Yeovil (52), Bicester & Woodstock (54), Romsey & Southampton North (59), Runnymede & Weybridge (65), Torbay (79), Stratford-on-Avon (83), Chichester (103) and Shropshire North (271), though this last seat is more plausibly a Labour target.

The swings needed by the Lib Dems to win these seats from the Tories range from 0.7 percentage points in Carshalton & Wallington to 19.3 points in Chichester, while Shropshire North would fall on a swing of 25.7 points.

The SNP seat visited by Sir Ed is Cowdenbeath & Kirkcaldy, which is much higher on Labour’s target list (number 33) than for the Lib Dems (number 186), while the one Lib Dem seat he has visited is Bath.

The two Labour seats are Hackney South & Shoreditch, which hosted the venue at which Sir Ed launched the Lib Dem manifesto, and Sheffield Hallam, the only Labour-Lib Dem ultra-marginal in the country.
