Category: Three-way Marginal

Geography: Wales, Gwynedd. The whole of the Anglesey council area.

Main population centres: Holyhead, Llangefni, Llannerch-y-medd, Menai Bridge, Amlwch, Beaumaris.

Profile: The seat is made up of the large island of Anglesey off the coast of north Wales and the smaller Holy Island. Apart from the industrial Holyhead it is large rural and agricultural and is largely Welsh speaking. The largest towns are Holyhead, a ferry port on Holy Island that serves as a major transport link to Ireland and Llangefni, the commercial and administrative centre of the island. The seat also includes RAF Valley and the Wylfa nuclear power station, planned to cease energy production between 2012 and 2014.

Politics: Ynys Mons (or Anglesey, as the seat was called prior to 1983) has been varied in its politics - it is one of very few seats that have been won by four different parties since the Second World War. Pre-war the seat had been a Liberal stronghold and was held by Megan Lloyd George, as the Liberals declined it fell to Labour in 1951. In 1979 it was won by the Conservative Keith Best, whose career was cut short after being jailed for making fraudulent share applications in 1987. Best was suceeded by Ieuan Wyn Jones of Plaid Cymru in 1987 but the seat was lost to Labour in 2001 after Wyn Jones stood down to concentrate on his Welsh Assembly role..

  1. Matt has a point as the seat of Caernarfon has been carved up like no other since 1945 – and the by-election the Liberals won was I think prior to the ending of the war, negating it

  2. By-elections count, defections only count if the party they defect to wins the seat at a By-election or GE.

  3. ‘Yes Ceredigion wouldn’t make my list as you can see above’

    I don’t think Ceredigion has ever had any form of Tory representation in its various guises since the mid-19th century

  4. Plaid have launched their GE Campaign in Bangor (an odd choice?)

    Ms Wood said they hope to capture this seat and Rhondda.

  5. With the polls as they are, this should really be considered a Con/Plaid marginal and not a Lab/Plaid one. Much like Berwickshire last GE, this is a seat closely contested by two parties hoping to gain the seat as the incumbent melts away.

  6. Maybe. But this seat has always behaved a bit weirdly. I wouldn’t rule out that Albert Owen somehow holds out against the tide once again.

    Ieuan Wyn Jones, MP here from 1987 to 2001 and AM for the equivalent seat from 1999 to 2013, has reportedly applied for the Plaid nomination

  7. This seat is a strange seat. Who knows who could win. Any one of three could win.

  8. Ieuan Wyn Jones has been adopted as the Plaid Cymru candidate for the June 8th 2017 election.

  9. I think that this one might be a Conservative gain. If Plaid fail to pick up Rhondda then this would come as a huge embarrassment for the party. Even worse if they are hard-pressed in Dwyfor Meirionnydd from the Tories.

  10. Ieuan Wyn Jones has a long-standing very high profile locally. He must start as favourite in the light of Labour’s decline in the polls. Not sure about the Tories – parts of east Ynys Mon are commuter country for Bangor and they have held the seat in the past. Their current surge in Wales might be enough if they can find the workers to cover the seat. I would be surprised if Labour held on. PC will get plenty of help from students in Bangor.

  11. ‘parts of east Ynys Mon are commuter country for Bangor and they have held the seat in the past.’

    Only for a couple of terms though – in the late 70s/early 80s under somebody so far to the Left they were barely a Tory

    Although with the way things look for the Tories in Wales they could be bettering it by taking seats like Alyn & Desside and Wrexham – which they’ve never won before

  12. If the last opinion poll for Wales, which showed a 10% swing from Labour to Conservative, proves half right, the Conservatives are in with their best chance of taking this seat since Keith Best’s surprise victory in 1979 (which is the only occasion the Conservatives have ever gained this seat?).

    Worth noting that Anglesey narrowly voted Leave (in contrast to Gwynned on the other side of the straits) and there is a 15% UKIP vote to draw on.

  13. But tough to know where that UKIP vote will go. It’s possible that some of it may go to Plaid, as the Plaid vote here is somewhat akin to the Lib Dem vote in Cornwall, more parochial than progressive.

  14. The latest YouGov Wales poll have Plaid falling back 2 points, Labour up 5 and the Conservatives up 1. The changes are from the last Welsh Poll about two weeks ago which sensationally put the Conservatives ahead in Wales.

    Using a universal swing (which I know is unlikely to happen all over Wales, let alone here) it gives the Conservatives the edge here.


    The poll puts the Conservatives on 41%, Labour on 35%, Plaid on 11%, Lib Dems on 7%, UKIP on 4% and the others on 2%.

    If that swing happened universally across Wales, Labour would loose 7 seats including this one to the Conservatives.

    UKIP won 13.6% in Wales in 2015 and their vote is now down to 4%. If the UKIP vote here goes to the Conservatives they could easily win it.

    Having said that, the Conservatives don’t seem to have picked a candidate yet and with the high profile Labour and Plaid candidates the Conservatives may struggle for local credibility here.

  15. For anyone interested a full list of Wales only polls, which specifically ask about GE voting intention, since 2015 can be found here:


  16. Are we expecting a three-way marginal here? That’d be my guess, with bests on Plaid.

  17. Agreed – three-way marginal with Plaid edging it. Maybe 1000 votes separating the top three.

  18. Looking at the cross tabs of that poll, 67% of UKIP supporters from 2015 are switching to the Conservatives.

    Far from an exact science I know, but add imagine if it happened – 3,431 UKIP votes switch to the Conservatives and they’re just 47 votes behind Albert Owen’s 2015 figure.

    And that’s before Labour loose any support.

  19. I do think there is an outside chance of a Con gain, but I doubt it’ll happen. Also depends on how many PC to Con switchers there are.

  20. Tory candidate lives in streatham….not sure that will play well in Ynys Mon.

  21. These things like ‘lives in Streatham’ aren’t always what they seem.

    But if it is in this case, that’s a stupid own goal in a seat Cons were otherwise favourites in.

  22. This has been one of punter’s favourite seats. I got 12/1 on Labour here, now 2/1

    Is there any intelligence from the ground here- evidence that Plaid are going after this seat in a big way? One imagines they will.

  23. Stronger than average swing to Labour here

  24. Ex Town Cllr and Welsh Assembly candidate Daniel Meredith ap Eifion Jones has been convicted of fraud and theft.

    He stole £614 from Anglesey Foodbank and received a 13 week sentence suspended for a year and was ordered to carry out 150 hours of community service.

    The ex Labour member made the Labour shortlist for the 2013 By-election but stood as an Independent most recently after failing to secure the Labour nomination.

  25. Albert Owen is to stand down at the next general election.
