Brexit and personal safety have been highlighted as reasons behind Welsh MPs standing down at the general election.

Six Welsh MPs have confirmed they will not seek re-election when the UK goes to the polls on 12 December.

Three pointed to political differences over Brexit and while two raised concerns over safety.

The sixth - 82-year-old Ann Clwyd, is the longest-serving Welsh Labour MP and has spent 35 years in the House of Commons.

Conservative Guto Bebb and former Labour leadership candidate Owen Smith said they were unhappy with their party's direction over Brexit.

Both have clashed with their respective leaders while Mr Bebb said the Conservative Party was "appealing to the type of nationalism" that saw UKIP and the Brexit Party grow.

Mr Bebb's colleague, Montgomeryshire MP Glyn Davies, said he would be "glad to see the behind" of Brexit following the impasse.

He added: "I come down to London on a Monday, spend three of four days [doing] nothing, go round in circles, make no decisions and go back home. I want to work."

Wrexham's Labour MP Ian Lucas admitted he feared his remain stance - at odds with his leave-voting constituency - could cost him his majority - which is less than 2,000.

He is also among politicians who have voiced their growing concern over their safety, which has worsened during the Brexit debate.

Ynys Mon MP Albert Owen said his constituency office in Holyhead had been repeatedly attacked.

"There are certain concerns that I have and many other people have for the safety of my staff, my safety and my family's safety," he said.

Which MPs are standing down at the general election?

Gutto Bebb (Aberconwy)

Originally a member of Plaid Cymru, co-founded by his grandfather Ambrose Bebb, he has represented the area as a Conservative MP since 2010 but has a majority of just 635.

In July last year, Mr Bebb, who voted remain in the 2016 EU referendum, resigned as minister for defence procurement.

This was in order to vote against the government on amendments it accepted to its Brexit Customs Bill.

No stranger to controversy - he attracted criticism for language used in public exchanges and a row with the chairman of his local Conservative association.

This political stalwart is the oldest woman to sit in the House of Commons having represented the south Wales valley constituency for 35 years.

She has held many political posts including shadow secretary of state for Wales, shadow secretary of state for international development and chairwoman of the Parliamentary Labour Party.

A champion for the coal miners during the 1980s and 90s, she was Tony Blair's special envoy in Iraq and campaigned on the NHS following the death of her husband Owen Roberts in 2012.

She announced she would stand down at the 2015 general election, but changed her mind and was re-elected that year, and in 2017.

The Conservative MP has served for nine years but has grown fed up with the Brexit impasse.

He said the "current uncertainty in politics" told him it was the right time to step aside after "going round in circles" for most of this year.

Mr Davies, 75, was elected in 2010 following eight years as an AM.

He served as parliamentary private secretary, or "Commons eyes and ears", to current Welsh Secretary Alun Cairns and one of his predecessors, Cheryl Gillan.

He lead successful protests against a pylon line across the Powys countryside and campaigned for the Newtown bypass.

Mr Lucas cited personal and family reasons for standing down.

In a letter to colleagues, he said the job had been a "demanding responsibility".

His announcement came just weeks after a man with a "vendetta" against the MP was jailed for 16 months for abusing his wife and public relations officer.

"I am 60 next year. I have been an MP since I was 40. I think the time is right to choose to follow a different path," he said.

He held a junior ministerial post in Gordon Brown's government in the department of business and had been an assistant whip.

He has also called for regulation of social media companies during elections.

An "intense full-time job" was how the Labour MP described the post.

He said his constituency office in Holyhead, Anglesey, had been attacked several times and "very serious" threats made during the Brexit debate.

"It's concerning and I feel for younger and newer MPs who are coming in and having to deal with this from day one because it's gradually got worse over time," he said.

Elected in 2001, he held on to the seat against Plaid Cymru in 2015 by just 229 votes before securing his largest majority of 5,259 over the Conservatives in 2017.

The 60-year-old has also served on the Welsh Affairs Committee and the International Development Committee during his time as an MP.

The Pontypridd MP said he was standing down for "personal and political" reasons.

He failed in his leadership bid in 2016 to topple Jeremy Corbyn, who sacked Mr Smith from the Labour frontbench after he criticised his position on Brexit.

Mr Smith was elected in 2010 and served as shadow Welsh secretary under Ed Miliband between 2012 and 2015.
