The all-round medium-pace swing bowler and right-hand batter was one of the first women to attend Nottinghamshire’s Cricket Academy and follow the county cricket coaching and fitness programme with fellow Notts players.
She has been playing club cricket since the age of 10, having first been introduced to the game at primary school and going on to play for Thrumpton WCC and Notts.
Gunn made her one-day international debut at the start of 2004 on the tour of South Africa and played in four of the five matches as England won the series.
She also made her Test bow that summer in the drawn match against New Zealand at Scarborough and retained her place for the World Cup the following year.
With the retirement of Lucy Pearson after the World Cup, Gunn was a vital member of the bowling attack for the visit of Australia the following year. She took seven wickets in the two Tests as England won the series 1-0 to claim the Ashes for the first time in 42 years.
Gunn toured Australia and New Zealand in early 2008 and helped England go unbeaten that summer.
She helped England to World Cup and World Twenty20 glory in 2009, although she had to withdraw from the 50-over final in Sydney on the morning of the game with a calf injury.
Gunn was then part of the England team that retained the Ashes with a draw in the one-off Test at Worcester.
Having been appointed vice-captain in June 2010, she led England in their second T20 versus Sri Lanka in Colombo that November as the tourists completed a series victory. She joined Yorkshire from Notts for the next season.
Gunn could not prevent England failing to retain the World T20 in May 2010 and the Ashes in January 2011, but continued to be a senior member of the side.
In July 2012 Gunn won her 100th England cap and at the end of the summer helped England finish runners-up at the World T20 in Sri Lanka.
Away from England duty, she has spent winters working on her game in Australia and writes a regular blog for ecb.co.uk about her experiences.
